Bug form PopUp not working

Hi there, 

My Jot form PopUp window only works / opens 50% of the time.

Hi,

I did not observe any difficulties when I tested both pop-up windows on the page that I mentioned in my experiments on the current version browsers, the problem you mentioned may be caused by browser plug-ins interfacing to the page content, like Adblock. You may try to disable that kind of plugins.

Also, consider to check out the guide below in the case of embed issues.
