We did actually look into this though as it never should have happened.
If you notice, your /jp output is clearly corrupted. The number of programs shows 207, the max is 14. This resulted in a lot of garbage being generated and the reply was never completing which is why there is no end brace. This is why the app didn’t load.
When you updated the firmware, it clears the configuration which removed the aberrant value of total programs. We have never had a report of something like this occurring and hopefully the newer firmware doesn’t have the bug that triggered this situation. If it occurs again, please let us know.
Thanks!
