How do I completely remove Margin Note 4 from MacOs?

I am having issues on syncing MN4 using icloud and I believe a complete reinstall on macos and download form cloud will solve that.

How can I remove all MN4 files, including folders on library etc?

Thanks!

Additionally, how do I do the same on iPad? I am having issues with sync there too

Hi, I have paid the MarginNote MAX and cannot use it because my library is not properly synced with MN 3. How do I perform above steps?

Thank you!
