Here's a mail Bernd Wachter sent to the SailfishOS.og Devel mailing list :

"Hi all,

we just discovered an issue in both 1.0.0.5 and 1.0.1.10 today which
causes update of the store token required for accessing store
repositories to fail. A fix for that has been pushed a few minutes ago:
The update to version 1.0.1.12 you might be seeing on your device soon contains exactly this one fix to keep store access working.

Bernd"
