Problem with connecting to “wanted” DVR source in APP

See screenshots:

RESULTS in: (Although the source is definitely on line for web UI)

This is with 2 DVRs running.
Can’t properly test between sources and beta vs current public (4 scenarios)

Do I really have to return to turning off the non wanted source?

You have to click "Connect to Channels DVR", not "Add Source".

OK, Sorry. Just getting frustrated with trying to test for the Transcoding problem.
