Mail-App in iPadOS 26 - Overview confusing
Since iPadOS 26 the size of columns in Mail is either too big or too small.
In standard-view the size of the Mail itself is so narrow you cannot read it. Or you make columns so narrow, that you cannot read either the folder or the "Sent from".
When you select "more room" in preferences you can see most things as used to, however the typo gets so small you can hardly read it.
