TypeError: Cannot read property "Lid" of null. URL

Computer: Mac and using the RemNote app.

I created a Document containing to-dos with /date next to each one.

Deleted the Document and got the following error message:

Something went wrong.

Please try refreshing the page. If the problem remains, please provide
