Form lag issue

A local company is providing a Jotform page for placing home delivery orders. I’ve tried filling it in on my iPad (6th generation, iPadOS 14.2) in Safari, Firefox and Edge browsers. Thinking it was a problem with my slow house internet, I also tried it on my iPhone in Safari, using cell data. Same problem each time.

The page takes about 2 to 3 minutes to fully load. Then as I start filling out the form, suddenly the page will reload and all my entries are lost. I tried to research this a little and somebody had mentioned a javascript issue. So I’ve tried it with javascript turned off or on but it doesn’t make a difference. The business said to make sure autofill is turned off, which it is. I tried clearing the Safari cache.
