Doorbell Pro live view not working on WiFi

A few months ago this problem started, and never resolved itself. Live view doesn't work when I'm on WiFi outside of home. On my home WiFi, it's fine. If I'm away from home on another WiFi, I have to disable WiFi to see live view. Someone else posted having the same issue with no answers, I'm hoping someone has an answer. This has nothing to do with the doorbell's connection at home. The signal strength is really good there. My WiFi signal in all scenarios was really good. I'm not sure if it's some sort of security setting with the app, but it used to work fine for about the first year, and then suddenly became a problem.
