Issue pairing after factory reset

Running into lots of problems. It started with no app being able to load. I kept getting the Wait or Close app pop and my left controller would connect no matter what I tried. So then I felt forced to do a factory reset. Now I can’t pair my device to the app. Says no device found (I’m on same WiFi networks). When I tried the support option and entered my serial number for my Quest 3S it said support is not supported for this device??
