Using an iPhone X.
When you select the groov View app it come up on the screen then blanks out (back to home screen).
If you up swipe you can see Groov View running but when selected it starts then we get kicked back to home screen. Basically it will not let you get far enough to select a connection.
Prior to 14.2 it worked and I have restarted the phone since 14.2.
Do you recall when you downloaded the app? I saw a similar crash on iOS 14 while testing groov View against the GM release, but it went away with a freshly downloaded copy of the app.
App was loaded a few years ago (its an iPhone X) and would have been been updated (if updates were available). Interesting to note that my iOS version is 14.2 not 14.2.1 and I get the Software is Up to Date when I check.
Just OFFLOADED (which will not remove the data for the App) and Reinstalled the App and it is now working. Thanks for the suggestion.
