Since the SIriusXM update to our 2017 S MCU1/HW3, the XM app has been excruciatingly S L O W...
After the update first installed, we lost our subscription and only received the preview channel - which is surprising since everyone is getting a free 90 day trial - so we should have at least had the free trial. But since we were already paying for XM, it looks like the upgrade wiped our subscription, didn't provide us the free trial, and we had to force a refresh to get things back.
Lost the favorite channels - and have to set those again. It looks like hitting the favorite star in the XM status window (with the forward/backward channel icons) doesn't work - I had to go down below into the channel list and hit the star there to add the channel into favorites.
Getting XM to start playing after returning to the car seems to be hit-and-miss - sometimes it starts playing fairly soon after starting, other times, it can take several minutes to start up.
There's a long delay when changing channels.
And whether it was this release or another recent release, have noticed that the MCU1 takes F O R E V E R to reboot. Starting a reboot using the steering wheel buttons, once the console display goes to black, it takes a very long time to get the Tesla logo displayed. And then it takes a very long time after the logo is displayed before the reboot is completed and the display and climate control start running again.
Compared to how the system worked a month ago - the latest software releases is a step backward in usability of the XM app, plus something is causing the reboot process to take much, much longer.
This release is yet another example of how Tesla's strategy for testing new software releases fails to identify obvious design flaws and bugs.
Tesla really needs to open their beta testing program, and allow more owners to opt in and help Tesla test new software better before distributing to the rest of the owners.
And when they release a clunker release like this, it would be very helpful if owners could "rollback" to the previous (stable) release...
