if you can, please create an issue for this specific problem at https://github.com/MbinOrg/mbin/issues if one doesn't already exist or thumbs-up/add a comment to an existing one so it gets visibility. broad fediverse compatibility is one of our main project goals, but not all platforms conform to the AP spec (or it's not addressed by the spec) and instead do their own thing, so it sounds like we'll need to work out a common ground.
