A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
Dear Tom Vanheems,
Good day!
I understand the mood very well. We are also very sorry for the long-term trouble caused to you by this phenomenon.
Due to the differences in the local environment, it is really difficult for us to copy the problems you have encountered here, and considering that you want to communicate directly with the developer, we suggest that you can use the Feedback function in the application, your feedback will be sent directly to the developer.

Thanks for your cooperation.
Sincerely,
Tin | Microsoft Community Moderator
