Trail Wallet 2.1.1 has been released to the App Store. This is a maintenance released that fixes a few bugs, especially a particularly nasty crashing bug that has recently appeared.
Trail Wallet 2.1.2 is also in the works to fix an issue with Dropbox syncing. This should be out in the next week or two.
As always, we appreciate your feedback and bug reports! If you do find anything that you think isn't right, please contact us directly rather than leaving a review on the App Store with a bug report.
We often need additional information to get to the root of the problem and, as we can't contact you or respond to App Store reviews, it makes it very difficult to find out exactly what the problem is and get it fixed.
