Before 01 may 2020, it was possible to search cases registers through the filter on the column "Filter by " with the operators ""on or after" and on or before, you were able to search a specific period of time ( a range of time ) for example: only cases created on february.

Now and with the new update for DYN , this is not possible anymore, the operators changed and now there is not any operator that enable you to perform this specific filter,
It's a very simple and common filter ( range of dates) is very weird and disappointed that now you can't do it.

i hope you can find a solution soon, or allow to us ( your client) go back to the last version.
