Network Connection and Ranked Issues

I have had issues logging into Apex, with a “Unable to connect to network” error. I followed all the troubleshooting, including clearing the cache, restarting my router, and reinstalling the game. The one time I did log into Apex, I can not play Ranked with my teammates. It says that I am rookie IV when I’m actually Plat 2. It will physically not able to ready up. Is there any fix to this?
