I appreciate your posting here; however, as you noted, deleting the app and re-installing it did work. But that was what I tried initially and had no success with. I contacted your Twitter support as well as having a phone conversation with someone in tech support, I believe. I did have a video of the issue that was submitted to Apple, but once re-installing the app restored a functioning app, I deleted the video. I’ve not had any further issues and submitted a revised review on the App Store, mentioning that deleting the app now works. As was noted in several reviews, that did not work early on. Unfortunately, when the app only opened to a blank white screen, there was no way to submit a report of the issue through the app, if that is possible. Anyway, all is well right now, but that issue continued for a prolonged time before it was acknowledged, allowing a large number of complaints to mount up on the App Store.
