I have a Galaxy Note 9 through AT&T and after the updated to Samsung's One UI update the hotspot and tethering stopped working. They would give and error of "Temporary network issue." I pretty sure that it is Covenant Eyes causing the issue because if I turn of the vpn and quickly enable the hotspot before the vpn is re enabled it seems to work. I also uninstalled Covenant Eyes and it worked fine. I reinstalled it with the most recent update and it stopped working again. I can hack it to get it work by disabling the vpn but I use it all the time so it is kind of annoying. Thanks!
