My second Brax3 is Wi-Fi only use. That new f-droid app from Iodé will not update any apps. Just sits there and spins.
Also glad I only updated my other phone to the 7.7 july1 update. It still has the regular F-Droid on it. And still works good.
The official final 7.7 is dated July 24. Anything less should be considered unstable.
Only the July 21 is showing up without the beta turned on.
Apparently there were some odd things happened in those 7.7 beta releases.
I don’t know if I should advise you to do a manual update to 7.7-20260724, or just wait for 7.8 which should be here Real Soon Now (also having odd things in the beta releases)
It’d be really nice if you could just easily revert backwards to an older version. 
We are not able to reproduce this issue on our end on 7.7.
A few things you could try:
- Clear storage and cache of the iode fdroid app.
- Install the f-droid from the official developer site.
Reverting back OS version is only available through a manual OS reinstall.
I don’t know if that last update automatically turned on everything reinforced in the Iodé droid app or if I had everything turned on, but I had to turn off the Wi-Fi blocking. Everything loaded after that. I always forget to check the Iodé app. By the way, can you tell Iodé to put in the permissions for each app?
