@JetForMe next time you experience this with a post, check that post to see if it’s coming from a non-mastodon instance. Feel free to send us a link to that post as well. The only thing we can think of at this point is you happen to be boosting a post from a non-mastodon instance and sometimes they do things a bit differently.
@ivory it’s 100% of the posts I boost, pretty sure they’re all mastodon instances, but I’ll check.
