Internet Calendars - Failing to show some recurring events from ICS-based calendars

I’ve been exploring converting to eM Client from Outlook as Microsoft continues to push the “new” Outlook, and while I’ve found feature parity in most of the important areas in my first day of testing, I did find what appears to be a significant bug in eM Client’s ICS protocol parsing for internet calendars.

I use a couple of ICS-based calendars for my work, and it appears that recurring events with changes made to individual entries (e.g., a meeting that recurs every Thursday, but has historically had to have some dates moved to a Wednesday or a Friday) often fail to show up in the calendar in eM Client at all (i.e., no recurring event and no sign of the changed event dates). It doesn’t seem to impact all recurring events with changes, so perhaps it requires a certain number of changes to have been made before it trips up, but it’s impacting several events in the calendars I’m testing with, so it’s clearly not just a one-off on a particular event.

I double-checked that using the exact same ICS URL in other clients (like Outlook or Google Calendar) shows the recurring events properly, and I double-checked the raw ICS file to make sure that the events are indeed listed in it.

Has anyone else run into this issue, and, if so, did you find a resolution you can share? Since these are private business calendars, I can’t share the links or files in full in their original state, but if you need any information or details from them to troubleshoot, I could probably create redacted versions of some portions of the files to share.
