Template editing not loading

Hi, when editing a template that I have created. Just plain pdf documents with editable fields.

Takes a moment to load, can see the spinning circles and then it loads for me to modify.

However if I’m done and click close on the top right, and then remembered I forgot something.

When I go and edit the template straightaway, it looks like it loads but then only a blank white page appears.

Have tried clearing browser cache and cookies. Have tried different browsers.

Same issue. It looks like I’ll be able to edit it again if I don’t try again for a while.

Is there any soluton to this as I don’t want to wait around in hopes I can edit it again.
