Pop-Up Reminders Not Displaying

Good day. I have eM Client install, version 9.2.1222 (ca10485), and am having an issue with reminder pop-up. I had an older version of eM Client installed (I don’t recall which but a recent version from earlier this year), that was working fine. I upgrade for the new feature which is when the pop-up issue started.

At some point in the last month, without any change to the version or any other programs, the calendar notifications and reminder pop-up window is no longer appearing. That means that if I have a meeting at 9 am, I don’t get a reminder window pop-up displayed on-screen. The same is true for reminders - I can schedule a deadline for reminders, and where I previously would have a pop-up window display at the day/ time of the reminder, nothing displays.

The synchronization does work in the calendar function, because I do get pop-up reminders of these events on my smartphone and in other devices that are synced with the calendar in eM Client (ie, if I schedule an event in Google Calendar through eM Client, a pop-up reminder will show in the Google account).

The only thing that I can think of that might be a software conflict issue is I have “StartAllBack” installed - which is a program that runs to change the Windows 11 desktop GUI to be more similar to Windows 10 (in how programs are grouped on the task bar).

However, the pop-up was working on eM Client when it was newly installed. I have also uninstalled StartAllBack and it has not resolved the issue with the pop-up in eM Client.

Your assistance in resolving this would be greatly appreciated.
