Ring app iOS v5.22.4 VPN problem

I run VPN regularly on my iPhone and all was well running it and accessing the Ring app on the phone until yesterday morning (Feb. 11, 2020). I opened the app and tried to access the features but coudl not. Eventually it kicked me out and I could not log in. I attempted to reset password via the app and it still gave me invalid credentials or an error message. I called Ring help and they sent me a reset link. When I tried to access that link via email, I could not. A light went on in my mind. I turned off my VPN and I could access all features, including resetting my password. Now all is well...except... I cannot understand why I can no longer access the app features when I am running the same VPN as before when I could access the features. I have the version number in the subject line. I don't know when this version was pushed to my phone. But it is clear that, it used to work while using VPN then, inexplicably, it stopped working. I changed nothing on my side so I can only presume it was an app update. But that is just a guess.
