Constant delinking of device on the discovery app

I have to relink my device to the discovery app almost every week because it keeps delinking. I’ve called discovery, used the chat option but this still hasn’t been resolved. I still have to delete my app and relink for me to get my points. I’ve been going through this for more than 6 months and it never gets fixed.

I’ve even changed phones but I’m still having the same problem. When you login to the app it says “update to the latest version of the discovery app” then it doesn’t show your vitality status. I then have to delete the app, re-download the app and relink it to my device. Two days later it has delinked from my device and I have to do the same process again and AGAIN to get my points. The discovery vitality program has become tedious and costly for me. It used to such great program until this. So inconvenient and so annoying!
