A recent update, 1 day ago according to Google, via the Beta-channel possibly, has removed the event's Edit (and Cancel, if I remember correctly) buttons from the top of the Event display dialogue on the Android version
That's the whole screen display, and the two big buttons at the top of the screen cannot be seen.
Much to my surprise, the button actions are still there. Tapping the right side of the black zone behaves like Edit, and tapping the left side behaves like Close.
I thought the other button at the top was Delete, which makes sense as there is no Delete option anywhere else on this dialogue, but it does not delete, just close. Luckily…
Also, in this last update, I noticed that the display selection button seem bigger than before.
Those Day/Week/Month/Agenda buttons appear to be using more vertical space than I remember. It mostly came to mind as the settings Cog button seemed out of place.
This is version 1.0.183 (1677) running on Samsung A54 5G under Android 15.
