@MartinK, @gaelic, what about making a backup on jolla phone, copy file to Tablet and restore backup?
Not having a tablet yet, I was planning to do it like that, so it would be great to hear if it is working!

Edit: Since 1.1.9.x there is even "copy to memory card" in backup-settings as a pulley option, so i suspect it is planned by Jolla to take out the memory card with backupfile from phone and stick it into the tablet to restore?
