form builder is not working correctly

For some reason this feature does not work, and when I do highlight a field with the solid blue and try to move it it tends to freeze and get stuck unplaced somewhere on the page until I reload. I need to be able to move a lot of fields at once with such a big document and so much copy and pasting of fields. And the field manager app also tends to freeze and not load or tends to misplace a lot of things when I try to use it.

We do apologize for the inconvenience.

Unfortunately, I cannot replicate the issue at my end.

May we know the web browser you're using to edit the form?

I would suggest you clear your browser's cache and let us know how it goes.
