I think the problem is that previously, we were not using UTF8 all the way and did not save enter properly. This has been correct, but still you might have Tasks and other settings with old format - which needs a reset. Thanks for heads up.
Today, the squares are back?? I had to retype the file write tasks and a notification body. 😳
I'm going to redo my steps...
