Me too from HK! Thought it was my problem. I passed Validation and Distributed to appstore. The build appears blank in testflight, but after sometime it disappear. After found this posts, now is Apple’s problem.

APPLE PLEASE TAKE ACTIONS! THIS IS ANNOYING! Big company Big RESPONSIBILITY

Some replied [by unchecking "Upload your app's symbols to receive symbolicated reports from Apple" ] I PROVED THIS NOT WORKING.
