Beta testers are unable to install or update Windows Phone 8.0 app in beta

Question

I have two apps in beta stage and now, probably after recent dashboard changes some of my beta testers are unable to install or update those beta apps. One of those apps was changed recently (using new dashboard), the second was unchanged for a month.

Error message on the phone: This app is not available for your device

• Testers are on the beta testers list, emails are separated with semicolon, all emails are from gmail with the same patters surname.firstname@gmail.com
• Both apps are WP 8.0 apps and testers have devices with WP 8.1
• Testers were able to install those apps about two weeks ago

Answer 1

In my case it was a bug. Microsoft fixed that issue, and now mu beta testers are able to update apps without problems.
