In the ‘Wednesday 2nd August’ post on [email protected] there’s a few complaints about how the links don’t open in Sync.
It looks like Sync only supports the ‘!’ method of providing relative links, and not the [Link](/c/community@instance) method. It’s the other way around for at least one of the other mobile apps (Jerboa, I think)
I’ve decided this is a Sync problem, but if that’s an unpopular opinion and it’s not something that the Devs feel the need to fix, then - if you really want to use a Community like trendingcommunities - the source for bot is available (see the sidebar), and it may well be that someone needs to create a alternative community with posts in the alternative format.
For what it’s worth,
!community@instancehas been a standard of sorts for Fediverse groups since 2018, when Friendica implemented them. Lemmy communities are simply Fediverse groups which is why they use this syntax, and I suspect it will probably be the one adopted by Mastodon as well when they do groups (although who knows? Whatever Mastodon decides is what will be standard across the entire Fediverse).
