InDesign 2020 v15.0.3 running on Mac Catalina.
When I type command-option-/ to refresh stories the refresh seems to go into a toggle mode swapping back and forward between correct and incorrect layouts. Very difficult to know if the correct version is working. Similar to the 2017 bug where table headers disappeared but even WORSE as the usual fix does not work consistently. Have to manually check EVERY page of document before sending to client as layout goes crazy.
