Next I wanted to check if the file that KP is using can be opened using my Windows PCs KeePass app. Proven by opening the file in "Files" - KP launches directly and has identical list of passwords. No change so KP is using a copy of the kdbx file as seen in the "Files" app. To check if the file was being shared between MKP and KP, I made a change to the passwords list in MKP, close the app and opened it in KP. That DB is now visible in the iPhones '"Files" app and it has the KP icon. In KeePassium (KP) I was able to use Add Database to open that database after entering my usual MKP password. In MiniKeePass (MKP) I saved the active kdbx to files "On my Phone".
