Dual partitioning as Android does it might have helped. Install the update to partition B, reboot and if it’s alright swap A and B partitions to make B the default. Boot again to the default partition (A, formerly B).
It wouldn’t have booted correctly afaiu with the faulty update, and would have been reverted to use the untouched A partition.
I thought I lost my Sonos integration with my music source. In fact it was just an update to the app and I don’t know how to navigate that… or maybe the new app just removed the integration
