Interesting.
I have a related, but slightly different problem - which may help explain the original post.
About 2 weeks ago, I checked the Mor Prom App to see when I had had my last COVID booster - in was it early August.
A few days ago, I tried logging in again to check the exact date of the last booster, but I could not get into the App. A message on the screen said "data loading .." I waited for about 10 minutes, no change. I thought maybe the MPOH server was down. I tried again the next day, and yesterday, same problem.
I thought that maybe tehre a problem with the Mor Prom App, so went to an app store to downlaod the app again. Found the app, but also a message to the effect that the new version of the app is not supported on my phone (an Oppo A37 which I purchased about 1.5 years ago).
Any comments?
