That works for devices which have a cell connection, but not for devices with wifi only. Had that issue with my Note20ultra and was able to get it to work, but my tab S7+ does not have sim capability and will not work with wifi off. Hope it helps some, but I'm still in the dark on the issue. Tried pairing my devices with Bluetooth and wifi to see if it would work using the cell connection, but no look. I, like many others will keep debugging, but it may take an update from Samsung for a fix.
