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.
ah, understandable. i’m a EE by day and all of the coding i contribute to Mbin is purely for fun with no bearing on real-life, so my github profile is expendable/only for Mbin. ;-)
