Hey, this is Jeff a developer from TGG. Sorry about this. We’ve had a few (like 4 or 5) reports of people with this issue. We have gotten some crash reports from Android and submitted a patch to fix the issue we saw there. Crash reports from Apple take a couple days to go through there system, so we don’t know for sure that is the same issue folks are having on iOS unforutnately, but it seems fairly likely.
That patch should be released for Apple devices any moment now (build 1629). When you get that build if things work (or don’t) could you let me know at email@example.com.
Again sorry about this and thanks for the report.
