Huge update indeed.
Went fine on XA2 and Tablet

XA2&10 AD upgrade to Android 9 is a good sign, isn't it?
I was guessing if the switch to lxc truly ment Jolla could now update the contained Android with less effort. Seems so?
Possibly they now find even more time to again revamp the notification system so it does not damn hide the status bar and a not so 90ish solution like drop shadows to give contrast

EDIT, Did not want to end negative. Digging through the changes, wow. Nice work Jolla. Much appreciated.
