Misplaced pin icons and shapes in Share for Review
Pins or shapes in Share for Review are always shown with misplaced icons or shape "borders". All browsers render it similarly. In Chrome, after reloading and clearing cache through DevTools, pin icons are changed to numbers and shapes disappear (in DevTools there is some error...). Btw, in Opera for Android, there are shown numbers by default. Using InDesign 15.1.1 for Windows, tried different files on laptot/desktop with the same results.
About a week before I used the function for the first time and everything was fine, but I'm not sure if InDesign had the latest update.
The issue has been fixed in the latest release of InDesign – InDesign 2021.
Please update to this new version of InDesign to get the fix.

Probably has been solved, works well now.
