Andre, Sorry if this is the wrong way to reply, but I could not find a reply button to hit on your response. I tried multiple times to do a clean install from the app store, the same issues persisted. On both my phone and tablet I now have no auto updates set. Then I download the 893 APK from this site, to my PC, and copied that to the download folder on both my phone and tablet. After that I used a file browser on both devices to do an install of the APK onto the device. In both cases that worked, and now I seem to be good again at version 893.
I'm sorry I don't have a lot of time to troubleshoot the problem, but too many things were wrong with 899 for me to live with. I hope MP can fix the problems and put out another fantastic version of the app. In the meantime, I have 893. Thanks very much for your response.
Best Wishes, Sincerely, Paul R.
