Our migration from AMS includes several thousand content key policies on import of these we noted -
1. The MK.IO UI struggled with more than 1000 with paging reporting that it showing "x of 1000"

2. Via the UI we were unable to Edit any of the policies and would always be presented with an error message.  (sorry I don't have the exact message at hand)
3. None of the policies appeared to work and trying to playback the video results in the DRM error message in MKPlayer

Its worth noting that these are all ClearKey STS policies.

To work around we deleted all policies bar one and used it for all of the streaming locators however this is less than ideal.

Are the above expected behaviour and is there an upper limit to the number of policies that can be created?
