Another hot, yet minor update arrived to my Jolla just now that forced me to make this urgent post.

This update according to Bernd Wachter is a minor update just to fix the small issue that was happening in the store previously.
Watcher adds at SailfishOS.org :
we just discovered an issue in both 184.108.40.206 and 220.127.116.11 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 18.104.22.168 you might be seeing on your device soon
contains exactly this one fix to keep store access working.
