I frequently have that problem with redgifs on the website too. Even when I go directly to redgifs. Just earlier today, I was browsing and more than half the gifs I was trying to view failed to load, or were very slow to load. I’ve been having this same problem with redgifs for as long as redgifs has been a thing. I don’t think the issue is with Sync, but with redgifs.
