I am having problem tracking the source of following exception on Android (no test on iOS):
When I set my MasterDetailPage mode to MasterBehavior.SplitOnLandscape and launch OR ROTATE device to portrait position I get exception (full stacktrace below).
When I use Page in landscape mode, it works OK, all icons are displayed, etc.
Looks like some layouting problem when menu is hidden.
I have no clue where to look for this error.
I even stopped populating menu - no items, but it didn't help.
Updated to Forms 1.5, no change.
