Quick question... (Patreon)

I've been noticing that thumbnails for videos i post on the Patreon app aren't showing up. It's just white. Are you guys seeing the same thing? Also, a couple people messaged me and said nothing i post is showing up on their feed (or wherever it's supposed to show up. i'm very new to patreon so i don't know about this stuff haha). But yeah that's concerning to me. I don't want people thinking i'm not posting anything. 😕 For example, i posted a behind the scenes vlog today. Are you guys seeing that at all? Thanks in advance!
