I posted about another issue with the teather app about a year ago and I was sent a beta build (1.2.1_250219) that fixed my issue.   However, after getting my new Iphone with WiFi 7, I wanted to make sure I was on the very latest firmware version (1.2.4).   

However, after upgrading the traffic usage broke and I am seeing no usage for like a good part of the day and then all the sudden a HUGE number is reported.   I know there was another post kind of like this but mine is a bit different due to he was getting usage just large all the time and I am getting large usage but starts mid day.   I am hoping there is a fix for this and I can be sent a beta build or this will be fixed in the next release.  From what I remember, I can't got back to a 1.2.1 build to fix this issue so I just have to wait.

Does anyone know if there is a fix for this (Reset Router on latest firmware) or something like that?   

I am hoping support and aknowledge this issue and find a resulution for me.

This issue is always fixed on the router side and not the teather app but I am on the very latest of that as well 4.12.24 (Build 1000)

Please let me know if you need any additional information.

Thanks.
