I've been having overall great success with my installation of GrapheneOS on my unlocked Pixel 7 since I installed a couple months ago, but I've had one snag that's driving me crazy. Every Android I've had since the Gen 1 Samsung Galaxy, I've used the original Swype keyboard. I've just found it learns better and works for me better than all other mimic Swype keyboards. Even after it was officially retired, I continued to sideload the same safe Swype + Dragon (last released, full-version) APK on every device through my Note 10 Plus 5G that just got replaced. I had no issues installing and using since 2017.
On my Pixel 7 with GrapheneOS, even when I've ensured "Install Unknown Apps" is enabled in OS and the Vanadium preferences, I receive a "App not installed as app isn't compatible with your phone." message. I REALLY want to get my Swype app back up and working for my sanity. Is there anything I am missing or something else I can try that I'm not aware of to get this APK to install?
