The compatibility checker has detected use of save events which may cause an undesirable experience during Real Time Coauthoring. Your solution may not work as intended during real time coauthoring sessions due to the higher save frequency during those scenarios. We recommend adjusting the solution to throttle during frequent saves. An alternative option would be disabling Real Time Coauthoring via Group Policy.
