Some Apps and web pages won’t connect after upgrading to iPadOS 15.3.1

Hello SnowSnake,

Thanks for your post to Apple Support Communities. We understand your iPad is having some network related issues after updating to the latest OS version. We'll walk through some steps to see if we can narrow down what might be going on. First, does the issue with mail seem to be specific to that provider? Do you have another account configured that works without issue?

When using a web browser, which app are you using on your iPad?

Have you tested both Mail and the Xbox Live apps you mentioned while your iPad was connected to a different Wi-Fi network or even using a Personal Hotspot?

Finally, we have some recommended steps for Wi-Fi connection issues. Walk through this article and let us know how your iPad is doing:

If your iPhone, iPad, or iPod touch won't connect to a Wi-Fi network

We look forward to working on this with you.

Best regards.

I have this problem too. I have two iPad Pro’s, one has updated itself to 15.3.1 and none of my 7 email accounts are now viewable. All are working just fine on my other iPad and my iPhone. The iPad that is no longer working for emails (it will not show any emails and closes itself when I try to open the page) is connected to the Wi-Fi- the same Wi-Fi as my other devices. I can do google searches, etc, without issue. I have tried the various ideas suggested on YouTube and unfortunately none have worked. Really need to get this fixed. Help!! I am a 66 year old non-tech self-employed person.
