With each new version of Pro, Esri releases helpful new functionality and improvements.
One observation I've made is: Standalone tables are sometimes overlooked when new stuff is released. If I had to guess, I'd say standalone tables might not be fully incorporated into Esri's testing process; not to the degree that feature classes are. So issues with standalone tables can get overlooked.
Idea: Could Esri enhance their testing process so that standalone tables get thoroughly tested too -- to the same degree that FCs get tested?
Edited:
I've removed the example (BUG-000155584) since that seemed to muddy the waters. For what it's worth, that bug isn't intermittent; FGDB views always fail when added to the map -- if the table is already in the Contents. It's the workaround that works intermittently.
