In the Upcoming Events block (like others), you can change from Grid to Featured to Rows etc, and can opt to hide images. How can I use one view for mobile and another for full view?

Different views per device are not possible at this time. If the block you're using can exist in multiple places on the same page and has the visibility option, you can duplicate the block and show the view you want to the proper device. However, if you're looking for a more streamlined solution, you will want to create a suggestion in our Feedback forum.

I wouldn't have thought of that. It works, but the Visibility tab doesn't appear dependably with two identical blocks on the page. If you keep saving and going back, it will work. Thanks.
