@firefish @oliver This is actually not true. The way our app is built is just unable to run services that use alphanumeric post ID's.

The update will roll out over the next few days, but you can grab it now here:

Once updated, just tap the smiley face icon in the compose window to view and select a custom emoji from your server instance.
