I hate to say it but every other system update Apps fails to process updates and new installs (apps/updates get downloaded but will not install). It was ok in the previous version but is not now. I’m using a Moto harpia.
It’s been suggested to use alternative repositories but I think Apps is a central part of the /e/cosystem and should work reliably.
Why does it get fixed regularly (previous version) and then fails again?
Have you tried more than one app to download? If not, please try a different app and see if it isn’t a problem with a single app. This is the problem I had and it turned out I was worried for nothing. I just had to create a workaround for that one app.
