Can't edit a document

Hello. I’m in trouble to edit my document on Dynalist web browser.
I clicked my document to edit on the left menu bar, then I found that I cannot type a letter to the document.
This issue happening in all of my documents since a few hours ago, although I can edit them from my android.
anyone has same issue?

Did you make your Dynalist window at one point? The lock mode was probably accidentally triggered.

Resize your Dynalist window to be narrow enough for the layout to change. If the lock icon is blue then that’s the case. Sorry for the inconvenience!
