Online Issues

Anytime I try to join a multiplayer session it says “Failed to join session” or “session no longer exists” this doesn’t seem to be a common issue as I have seen anyone else with an issue like this and I have tried resetting the Wi-Fi on my PS5 and turning off my router and deleting and installing the game again, this is really the last solution I have as I am very disappointed that I am unable to play online after purchasing this game as I enjoy playing online against others. Hopefully this issue can be resolved as quickly as possible. Thanks for reading.
