Yes, internet access is the issue as described in this post https://zubersoft.com/mobilesheets/forum...296&page=3 which you posted in, so you are aware.  I'm not sure why Bluetooth would impacted though - that shouldn't be happening, but Bluetooth isn't always as reliable/stable on every device I've found.  There is no option to force Android to stay on Wifi without the steps described in the other post. We can definitely focus on trying to resolve the issues with Bluetooth if you can't get that to work. You do have to pair together 9 tablets at once, so I'm not sure how well that will work as I've never tried more than about 4 or 5 (but encountered no issues when testing that).
