I was using R20 while our city was on lockdown in March-April. Our group meets on Fridays every week, and we were unable to during that time. No one could get the audio working properly, although the proper instructions were being followed (I think). Only myself and my fiancé could regularly make conversation using R20, so we moved to Discord. other than that, it seemed to work very well for dice rolling and character sheets. I was impressed, and I still think it’s likely issues with group members’ equipment that caused a lot of the issues. Two of those who had issues were using $40 Android tabs on 6 or so year old versions of Android trying to use R20, and those same folks had issues with Discord frequently just shutting down.
