App says it's installed, but it isn't and

[GalacticChode]

I'm an android user running lineage OS on a OnePlus 3T and I'm trying to install the Ally Mobile banking app from the google play store. The installation will not complete, I've tried several times.It says it's already installed. When I attempt to reinstall, it says the app will be installed shortly, but it never does. I know the working solution for most normal android users is to clear the cache in google play services, however that's not an option for me as a degoogler. I'm trying to keep my phone google free, hence the reason for using Lineage OS. I tried clearing the cache in TWRP, no luck there either. Any thoughts or suggestions would be greatly appreciated. Ready to put a fist through the wall over here!

Is your device rooted? I know a lot of banking apps don't work right with root for security reasons.

Welcome to Android Central! I moved this from the Android Apps forum to the OnePlus 3 Rooting/ROMs forum since the former is intended for developers to promote their apps.
