DynDOLOD and TexGen create a summary of some similar warning and error messages for easier review and better understanding.
It does not substitute having to pay attention to all log messages.
In case there were matching warning or error message printed to the log, the summary should automatically be opened in the default web browser once all steps of the session ran.
Otherwise open ..\DynDOLOD\Summary\[DynDOLOD|TexGen]_Index.html. If there is no such folder or the summary wasn't updated in the last session, it means there were no matching messages or the processes stopped prematurely - which would be evident by error messages.
Read the explanations for each warning or error message to understand their seriousness - it ranges from negligible via causing visual issues to CTD - and to decide if action is required to fix the causes of the reported problems.
