I count three people who are reporting/confirming this issue... Checking my phone, all permissions seem to be the same as before the big update. I don't use Aurora.
I tried installing an app with Aurora, removing the network permission, then updating the app. After the update, it still didn't have the network permission.
If this is indeed a problem, then it needs to be something that can be reproduced, otherwise how can the developers get to the bottom of the issue? It could be helpful to know specific apps, Aurora's version, owner / a secondary profile, etc.
Having said all that, I really don't see how this can be happening. I can't imagine how apps updated via one specific app would be the only ones that have had their permissions suddenly change while other apps' permissions remain the same as expected.
