We just discovered an issue in both 22.214.171.124 and 126.96.36.199 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 188.8.131.52 you might be seeing on your device soon contains exactly this one fix to keep store access working.
My Jolla arrived this morning, and I've been playing with it all day. It is by far the most exciting device and operating system I've used in a long, long time. When it arrived, the first update
to the operating system was already waiting for me to be installed - and only a few hours later, another update is hitting the device. They have promised another large bugfix and stability update
before the end of the year, with updates with new features arriving early next year.
These men and women know what they're doing. They're not overselling, and they keep their promises. A very promising start.
