I have been using V2.1.0 and it has been working very well. Updated to V2.2.0 this week and I no longer receive preview images on my tablet. I also have an S20 Samsung phone and it continues to work.
There has been rumor that the RAM requirements have changed with V2.2.0 from 2gb to 6gb. If so, please provide a method of downgrading back to V2.1.0, as I have no need to buy a tablet at this time. I use my existing tablet for outreach using the Seestar S50 and, while I would miss the latest features, Version 2.1.1 works well enough for me.
