Play Store couldn't install app

ofelei

I had a couple of apps installed on GrapheneOS which I used without problems.
I unistalled them a couple of days ago for security reasons (banking apps and email) on my pixel (using the Play Store) and now I cannot install them anymore. The Play Store lets me download them but then the installing process doesn't go through, and no "Do you want to Install this app?" pop-up appears.
Is there anything I can do?
Thanks

Just a guess:

Do you have these Apps in a user profile (not in the owner profile)? And if so: Is the following deactivated: Settings> System> Users> Profile causing problems> App installs & updates?

If so: End the user profile with end session, set the above mentioned setting to enabled for the corresponding profile, restart the profile and try to install these apps again.

Just one user (owner)

ok, I think I fixed it. I uninstalled the Play Store and installed it again. It asked me permission to download unknown apps. It didn't work while allowing it through the settings

Not true, I didn't fix it, the first app installed ok, the second app did the same "Couldn't install app" message. No pop-up this time.

Any tips on how to use the Play Store without having to uninstall it and install it again before downloading each app?

I've the same issue. worked fine for months and months until couple weeks ago, inside sandboxed profile, don't think I changed anything myself, but auto updates and auto remove permissions seem to be enabled by default. Can install updates fine, cannot install new apps. No popup for install, only 'Installing...' followed long after by popup 'can't install {app} see common ways to resolve this blah blah' however there is a gmscompat notification (not popup) upon installing the app 'Action required in play store' clicking on it just pulls up google play store.

I'm experiencing the same issue.

I'm trying to install the Facebook app through the Play Store and I'm getting the "Can't install Facebook" error.

It's good to know I'm not the only one facing this. Hopefully, someone has a solution we can both try.

This issue has been plaguing me for months ; reading this thread inspired me to do some troubleshooting and come up with a solution. It also motivated me to create an account and share my insights.
First of all, there's no need to keep reinstalling the Play Store as @Ofelei suggested. Simply go to App info then stop the app then Clear Cache then Clear Storage. Make sure Allow from this source under Install unknown apps was off before you did this.
Now, proceed to switch on both Allow from this source and Allow access to Android/obb folder. You can then open the app and install apps in perpetuity, hopefully.

I've tested my solution a day later and, unfortunately, it does not stick.
