When I try to open a file in the Android application, it displays an alert box with the message “The chosen file’s location cound not be found. Does it exist?” and an OK button, and does not load the file. This happens for various files (.kra from a 2.9 Linux Krita, PNG images) and for any location (internal or SD card).
For a single open attempt, there may be as many as four such dialogs in sequence.
In fact, I could only open one file, and then after that, only reopen it through its “recent file” link.
