Yes, enabled ECO mode in the afternoon, and during that time from LED in system log IOT 5G went down, but you don't see it in log.

Hi, I had it switched off, but I saw that after update it was switched on again, didn't noticed that. Switched off again, but also ECO mode switched off now and still working ok.

I've no issue with any Tuya here : 2.4 Ghz with WPA2-PSK[AES]+WPA-PSK[TKIP] and 5Ghz with WPA3-Personal+WPA2-PSK[AES] Have no issues what so ever, but if 5 still doesn't connect also put them on...

Can be they only use WPA2, I also have Tuya without problems.

@Joseph-TP Ok , have the latest also installed, but noticed at exact sametime my IOT WiFI 5G went down around sametime as LED. I switched to Smart ECO in the afternoon after updating. System log said...

They should do all which HW can support, you introduce something, then you can't do a half testing beta. If you know upfront which don't, name them, simple.
