Smartthings v1.7.85.25 No Longer Streams to Roku Device

As the subject says.
Running Smartthings on a Samsung Galaxy Tab S4 (SM-T830) trying to stream to a Roku 3600X-Roku Stick Software version 11.0.0 build 4193-24 results in the Smartthings app showing STATUS as AVAILABLE. There is no option to connect to the Roku stick anymore.

This was working previously in the days leading up to May 28, 2022 when the symptoms described above were encountered.

Please help me understand what changed.
