System Notice – Network/Server Issue?

Hey everyone! Is anyone else getting this system notice when attempting to play on mobile data and not WiFi?? My WiFi allows game to function fine, but when I want to play and don’t have WiFi, I keep getting these notices!

Any tips? (iPhone user here).

Already tried the manual DNS configurations, offloading and reloading app, restarting phone, airplane mode, def don’t have at VPNs on..
