The latest update has improved the bottom 3 button Gesture navigation but is still not right. The confused moderator in the discussion section said to post here for whatever reason.
The swipes still do not always register. It needs to be fixed. It's not a suggestion, it's a requirement. It worked fine in 2.5 and doesn't in 3.0.
We apologize for the inconvenience. Please send us an error report to help us debug the issue. We appreciate your contribution to the beta program.
