WiFi Logged but Not Connecting

I have been having several issues with my iPhone XR. Initially, I could not access Maps, Safari, or even my Apple ID unless I was connected to the internet. I restart my phone several times to no avail. Finally, I reset my phone only to be told that my Apple ID could not be verified. I had to connect to Wi-Fi for it to connect. I cleared the cache in Safari and that allowed me to use the aforementioned apps for a few hours without Wi-Fi. The problem soon resurfaced. I reset the network settings. That did nothing. So I erased all contents and settings. Now I can use the apps without Wi-Fi, but now I cannot connect to the Wi-Fi. I am currently logged on to the Wi-

Fi but it doesn’t show the connection. I have the latest update. This happens on my home Wi-Fi and work Wi-Fi. How do I fix this problem?
