BUG: Update is temporarily removing thumbnails

[JJ Jones]

After the last update, when I add a new photo to a card, it automatically removes the thumbnails. I click off the card and come back, the thumbnails return. Can this bug be fixed. Please and thank you.

Also, please return the "remove cover" option, under the three-dot box by each image.

Hi JJ! I haven't been able to replicate this one quite yet, could I trouble you to share specific steps you're taking when the thumbnail isn't appearing for you?

Are you dragging-and-dropping the image to the card back? Or, are you attaching through the Add -> Attachments -> Select a file option from the card back? Or another method?

I tried upload with both of those methods, as well as within a Comment, and each produced a thumbnail.
