We use a mobile iOS Application which is connected a SUP 2.1 Server. The Application runs fine until a couple of weeks but now we got some synchronisation problems. Some users don't get data changes on their devices.
Probably we have identified one possible reason for these synchronisation problem.
In the CDB we have duplicate entries in the mm_rbs_subscription table. Duplicate means, that for one device_id there are two or three remote_ids in this table. We dont know the reason, but we assume that these entries were created during our iOS7 Migration.
Maybe this entries are one of the reasons for our current synchronisation problems.
Did anybody know, how which entries would be created? And is it possible to delete entries in the mms_subscription table?
