'Can't complete the action' error when trying to edit documents

[knoble14]

Hello. I've been editing several documents and I added some text over but now I can't remove some of the texts. I tried with several documents and some of them are working and some are not. It's displaying this message: "

Can't complete the action.

Something went wrong. Please try again.

I tried several times and different document but it's taking some of them and not saving the others. How do I fix this issue?

Hi there, @knoble14, thanks for bringing this to our attention.

What kind of documents are you editing and how are you editing them?

If you're using the Dropbox website, try from a different browser or a private browsing window and let us know how it goes.

Thanks.
