@feditips Ah, thank you! I look forward to having a backfilling option. As a photographer who uses Mastodon to find other photographers, the limited backview has been (mildly) disappointing. But the browser is an okay workaround.
It makes sense that backfilling could, sadly, be a resource hog on a server.
Re: "If one person on your server has followed the account, all the posts after that moment should be visible from your server. However, anything before that may not be."
This doesn't seem to be in effect here yet. If I look at, say, @kylev, for example, any media he has posted older than 24 days only shows as a blurred gradient in the app. But I and others on my server have followed Kyle for a long time. It seems boosting keeps media alive on my server, but simple following does not.
Again, thank you for the quick answer!
