Error Code 8

Device: iPad 7th Generation
Operating system: iOS 18

I recently updated my iPad from iOS 15 to iOS 18 in order to experience 26.1. After updating I have been receiving error code 8 every single time I try to open the app. According to my app store, the app is up to date. I have tried restarting multiple times, deleting and redownloading the app, and resetting my network connection. My WiFi works on the iPad, and I can use Google and other stuff, as well as on my phone. I have connected to my phone hotspot but IF didn’t work then. Any ideas? Thanks

Been working at this for a while. VPN doesn’t work either. I’m thinking of bringing the iPad down to iOS 17

Got it to work. For others experiencing this, go to settings and erase all settings. Thanks chatGPT
