BE805 (BE19000) new OTA firmware feedback? (1.2.0 Build 20250304)

Seems that this new auto-update firmware just dropped in the router GUI. I've held off for now:
Update notes say:
Modifications:
Enhanced wireless performance of the device.
Enhanced security of the device.
Fixed some issues with displaying anomalies.
Fixed the issue that the phone associated MLO network abnormality in some cases.
Fixed the issue that IPv6 cannot access the Internet in some cases.
Fixed the issue that wireguard VPN client may not be able to access the Internet after DoT is enabled.
Fixed the issue that the corresponding client cannot access the Internet even after family time is over.
Note: After updating this version, it is not possible to downgrade to a previous firmware version.
Right now I am using three units in my house, all with MU-MIMO turned off (OFMDA only). If I turn that on, all SSIDs can disappear abruptly any time within the next 48 hours. Easymesh is off and will never be used as the entire house is wired. My network has been very stable for the past few months though without MU-MIMO. Not brave enough to try the upgrade, or at least not yet.
Would love to hear from the community if anyone has upgraded and can share their experience thus far.

Hello@Corpski,
Thanks for your reply.
So,it is not easy to move other devices, which will have a great impact on the entire network.
Then let's do some basic troubleshooting between the iPhone and the router:
- Have you checked the QoS settings? Is it possible that you have set speed limits for both iPhones?
- Please try to connect the phone to different router units, is there a difference in the phone's download speed?
- Check if the phone itself has a speed limit set?
- In addition, will the download speed of other non-WiFi 7 devices also be lower than the upload speed?

No QoS settings at all for any router.
Phones get the same test speed result regardless of which floor I'm on. Phones don't have any speed limit set.
There aren't really any non-WiFi 7 devices in the network of note. Most are smarthome or single-purpose devices that just send brief burst commands. All streaming devices are hardwired but most of them cap out at 900-1gbps over wire (they will be slower in wireless mode of course).
So far no SSIDs have gone down yet since the last instance. Perhaps it was a fluke given some unique instance.

Hello@Corpski ,
Thanks for your reply.
Please confirm the link speed of 5G: How to check the associated/link speed on a wireless client.
Please use WiFi analysis tools (such as WiFi Analyzer) to scan the surrounding channel congestion and manually switch to an idle channel for 5Ghz.
If the issue persists, we recommend sending an email to support.forum@tp-link.com with the following information:

Would you know of a way to revert to the latest stable release? The same unit exhibited problems but it's an odd kind in that the SSIDs are showing but a number of devices could not join either network all of a sudden. Instead of the SSIDs disappearing, they were there at full strength but were rejecting wireless devices. Walking to an area that had coverage from a second router resulted in joining the network at a weaker connection strength.
A reboot fixed the same router that had been experiencing issues. This seems is the second time something happened so it doesn't happen often.
Still, I'm rather fatigued from all this and would just prefer to revert to the last version which had been stable.

Hi@Corpski ,
Thanks for your reply.
This does sound regrettable. If you want to downgrade to the previous version, you can go to the US official website to download it: Archer BE805(US)_V1_1.2.2 Build 20250424
However, the feedback from using the new version of the firmware is also essential to us; your case has been transferred to the engineer before. If you are willing to continue troubleshooting, the engineer is also happy to follow up on your case. You can reply to the engineer through the ticket with an update on the latest situation. Your ticket ID is TKID250439957.
Of course, if you do not want to continue troubleshooting, I also respect your choice.
Thank you again for your understanding and support. Please don't hesitate to reply to me if you need any help.
