Glad y'all are enjoying this feature. A small number of you are reporting that Mastodon accounts are not being recognized as such in our UI.

We make a NodeInfo request to non-obvious hosts to check server metadata. Requests to some hosts are hitting our aggressive timeout. We're working on making this process more resilient.

You may have better luck by removing and re-adding the link to re-trigger the check. In any event, links will still function as expected, even for verification.
