hah, I've spent quote some time on changing the root path for the SD card (SD card's ID) as I that thought it was to blame
If I already have few ratings and stats on the new device - could ratings import fail because of that, or is there a merge mechanism? I don't mind loosing these fresh ratings as there are just few of them.
Full rescan also does not help, and deleting apps data through system's app manager also no longer an option (as it leads to PA's full rescan option).
If anyone has any other ideas I'd appreciate.
p.s. source device was running older android version, target is v13, but I doubt that should be an issue.
