    The 2 reports, in full

    1.15.20.4403 for Luba 2 AWD have broken obstacle detection. Since upgrade the robot is afraid of slightly higher grass than usual. TLDR; nagged at chat, uploaded logs just after robot being stuck, today I got 1.15.21.1 in the app. Should be fixing that. I'll upgrade probably tomorrow after finishing one large zone. Temporary workaround is to disable obstacle detection completely, which is as bad as it sounds.

    My Luba 2 is also behaving strange since this update to 1.15.20.4403: while charging the red side LEDs start blinking from time to time, stopping it after some seconds, to do it again after some minutes.

    That's everything we have — and neither report is a clean run. We'd rather show you 2 real reports than a made-up percentage; if you're on this build, yours is the report that moves it.
