I still use the legacy dev console most of the time because whenever I've tried the newer console it has always given an "Internal Error" when trying to view datastore entities or view to Queries section.
I was hoping the new, more colorful dev console would finally fix this problem but it gives the same internal error.
The only thing I don't get errors for is looking at Datastore Indexes. That seems to work fine. But Dashboard, Query, and Settings all fail to load with the same "Internal Error".
Please let me know if there's anything I can do to fix this. I'm very worried that you're going to completely decommission the legacy console and then I'll be unable to support my users.
Thanks,
Stephen
