It looks like the albums are actually created, BUT they appear at the end of the album list and no album thumbnails appear

This is related to my other topic: https://invisioncommunity.com/forums/topic/479280-bug-4718-beta-3-new-gallery-albums-appear-at-very-end-of-list-do-not-generate-thumbnails/#comment-2975945

 

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
