Anyone else have a problem where the middle screen freezes about 20 seconds after startup and then reboots itself after a couple of minutes? getting quite annoying...

Definitely a fault that a possible reload of MBUX might fix, or possibly requires a hardware replacement. Either way, get it back to the dealers...

I am in Canada with the A250 and I have experienced the exact same thing and not just once. However every time the dealer claims they can't reproduce the problem so I have recorded a video of the reboot. Going to gather a few more videos and will bring it in again

Happened to me once - nav screen froze right after a cold start. Nav guidance was active and talking but display hung. Auto rebooted too after a minute or two.
Must be a watchdog timer in there so at least it can recover.
FWIW my 420d used to do this every hundred hours or so, and so did a 2014 E Class.
No hardware issues on them either.
