Yes, I too am experiencing the same issue on three different devices.  Two are iOS and the other a Windows 10 environment.

I am getting this identical problem on Windows, macOS, my iPhone 6s

I am getting the same error and it’s getting extremely annoying.

After having constant email issues with tpg I am slowly moving away from them, too unreliable.

I have been having same issue on my iphone 5se and home pc-it is frustrating and very annoying. More annoying because the issue is not recognised on the tpg service status-very poor service!
