Sometimes when editing an Activity page and adding a tile I select a particular tile to use and then change my mind when I see what content fields and configuration it allows. There are many tiles and I haven't memorized what each offers. At that point I would like to Cancel and pick a different tile. I haven't entered any information or made any changes in the window.
There is an Apply or Done or Save button (very inconsistent) on the configuration window for each tile -- but no Cancel button. If I click off of the tile configuration, the tile type persists. It seems I have to Apply and then Delete the tile to add a different one. This is clumsy. Is there a better way to do this?
Unfortunately, there is really no other way to get rid of a tile you don't want. The easiest, as you've figured out, is to just click off and then use the trash icon to remove it.
