There are a couple of issues with the message box on UiPath.System.Activities 22.4.5.
It’s working fine if downgrade the package to 22.4.4.
Issue 1. AutomaticallyCloseAfter no longer works on this release. It doesn’t close automatically.
Issue 2. The message box appears later than the sequence expected to come after.
Yes, in fact, I encountered the issue after upgrading to 2022.10 releases. Done some backtracking experiment with the packages and found that it all started from 22.4.5 version.
If you look at my original post at the top, it is already sets to 2 seconds in the picture.
One correction though, it worked until UiPath.System.Activities 22.4.5, and started failing from the subsequent release.
