I have created a safe on the SD using the files app on my Huawei P20 Lite. It worked fine, until I decided to create a second one. Now, it no longer asks for my fingerprint, but for my password. After entering it, it brings me to a safe selection screen. Selecting the one that is in use does nothing. Selecting the other one brings me back to the password entry screen after which the process repeats. I have tried deleting all but one safe from the SD card, and resetting the password. Both methods do nothing. Creating a new safe lets me add files to it until I exit at which point the process repeats.
Q: How do I enter a safe or reset it entirely so I can create a new one?
