Mobile Link very slow

I have Mobile Link on my Android phone. I am having an issue with the app running incredibly slow after riding Zwift for 30-40+ minutes. Works fine early on. The longer I ride the slower the app gets. ANy ideas?

Hi Paul, 

This sounds like the phone’s issue. Perhaps warmer it gets, slower it’s operates? What about other apps? Have you tried any? What phone do you have? 

The phone is a Samsung Galaxy 4. It works fine on everything else. Funny thing is yesterday I rode for slightly over 2 hours and it didn’t miss a beat. Also it has worked fine on some rides (usually shorter), others I experience the slow down. 

Hi Paul,

That’s pretty strange issue, have you tried reinstalling the Zwift App?

I did re-install the app. No change. Another thing I noticed is if I have to go to a different screen, for example to see my count down clock for the start of a group ride, then go back to zwift the Chat function does not display what others are texting. I can send a message and see it appear on zwift, but the no more text come to me on the phone. This weekend when the app got slow, I logged off the app, logged on and it was working fast and normal again.
