@here Thank you all for your patience. And most of all thanks to @jemcallister1 for lending his unit for some time
We managed to find and fix this bug, we will do our best to include the fix in the upcoming Play/Play+ firmware update.
For the time being, please accept this “beta” firmware with the fix. Mind this firmware may contain other bugs! We usually try not to leak unfinished and untested firmware, but in this case, we decided to make an exception due to the circumstances.
