Hello,
I thereby confirm that we are looking into the issue you have been reported and that we are tracking the problem.
Please, note that the app description did not claim OneTeam is working with Prosody.
From the product description: “Supports: ejabberd, openfire, jabberd14, jabberd2, iChat, Gtalk”
This list is missing Jabber XCP and we will add to the description, but yes to be frank we did not test it with Prosody, because no one ever asked (until you posted there) to support Prosody.
To investigate further, we need you to provide a test account on your server to connect with OneTeam and check the problem.
Regarding the push system, Apple requires our developer certificate that we use to generate the application and we have not the right to delegate the push to our applications, as explained in this forum.
