Hi all,
On the Windows app, when the mail is shown grouped by the received day (Today, Yesterday, A week Ago, etc.), by default all the groups are expanded.
If you collapse the groups, move to a different folder, and go back to the original folder, all the groups get expanded again.
A folder view should be remembered, and shown as it was before moving to a different folder, or, at least, have to option to “collapse all groups”, as view settings, so when you move to a folder, the groups are shown collapsed.
Cheers.
