THANK YOU! 
That’s such a relief!
I should add, using the UWP Share feature will fail your app, this happened to my apps recently and as almost all my current apps make use of this feature, I had to skip XBOX as a platform, hmm I do have one that does not use such a feature, will try to add it to the supported platform list and see if it throws any other fails on my next update…
But as long as you do not use the share charm feature, you should not have that issue.
