I installed Graphene OS on Pixel 7 Pro over a year ago and had no problems with apps working. I couple of months ago that phone's motherboard crapped out on me. So I bought another Pixel 7 Pro and have installed Graphene OS on it and a number of apps are not working well or at all. Here are a list of a few apps that no longer work or work well;

Albertsons
Vons
MagicJack
Lead Connector
AdAway

Does any body have any suggestions on how I get these apps working again, please?

If you want help, you need to provide infos. GrapheneOS (unlike standard Android) has a log viewer for app logs and you can also always see the system log.

That is useful info.

And I never heard of any of these apps, so what they do, how you installed them, what they do instead
