Note 20 Ultra and S20 both on T-Mobile US. Both in the last couple of days get constant notifications that wifi preferences have been set to cellular. It won't stop, triggers multiple times a day. I've searched, set silent notifications, nothing helps. Google search shows this same issue for others related to Samsung and TMO, most finger pointing at TMO. As of yet this is unresolved. The only way to stop it is to turn off wifi calling which is not a solution. Any others experiencing the same thing?
