Version with bug
8.0.80 SR8
Is this a regression from previous behavior?
Not sure, did not test other versions
Last version that worked well
Unknown/Other
Affected platforms
Android
Affected platform versions
Android 10-14
Did you find any workaround?
Override OnAppearing method of every page with toolbar, clear items and readd them.
protected override void OnAppearing()
{
base.OnAppearing();
var tb = ToolbarItems.ToArray();
ToolbarItems.Clear();
foreach (var item in tb)
ToolbarItems.Add(item);
}
It plugs the hole, but require to be included in everypage, not mentioning additional perfomance overhead.
