Offline to only one friend while online and vice versa

My friend and I can only connect too each other’s worlds if it’s a LAN world. This is because the game says that she is offline while I know she’s on and tells her I’m offline while I’m on. We are both connected to WiFi. Even weirder it only my one friend with anyone else it works just fine.This happened after an account glitch I had where I couldn’t sign into any account on my mobile device. It was fixed but then this happened.
