FWIW GotoSocial seems to work (although Ivory is showing that timeline under the wrong user for some reason - all the GtS timeline posts are shown as the user I logged into the Akkoma instance with.)
In summary, if you're not using a Mastodon instance, probably give it a month or two.
EDIT: Having said that, it's showing every timeline item on the GtS instance as the same one - I suspect they might be using integers for IDs (which is what Mastodon - but no-one else - does) and coincidentally this timeline has IDs that all start with `01`. Which would also explain the Akkoma problem since all those IDs are currently starting with `AR` and thus unparseable as integers.
None of the iOS Mastodon apps (except one that is proprietary and seemingly not published on the german appstore) properly support Akkoma notifications, but a somewhat broken Ivory would still be better than a halfway broken Metatext.
Depends how you implement it. e.g. If you use `int64` for your IDs, Akkoma and GotoSocial won't work. Or if you send your POST parameters in the URL, Akkoma won't work. There's other subtle stuff too - toot codes unset optional fields as `null` in the JSON it sends (rather than leaving them out) which breaks both Akkoma and GotoSocial.
In summary, someone needs to write a decent MastoAPI spec and get everyone to agree on that rather than this ad-hoc balkanisation.
Description: ID of the status in the database.
Type: String (cast from an integer but not guaranteed to be a number)
Version history:
0.1.0 - addedIn other words, even the Mastodon API docs claim the ID isn't guaranteed not to be a string.
I'm sure there are undocumented differences, but if you base your data model on the spec then there's no reason to even assume you can just use a number.
Toot! seems to work with Akkoma/Pleroma now, but notifications are still somewhat lossy.
