[OnePlus 8T ROMs, Kernels, Recoveries, & Other Deve] q-quan:
Although the install went well (and most things seem to be working great), my banking app crashes when attempting to log in, while on my previous install of LineageOS 20 it worked perfectly. It seems to be a vague keystore error that has been mentioned occasionally for ROMs and devices, but I don't see a solution other than for ROMs to be updated with a fix. Any ideas are appreciated.
