Form: when you upload a file the form times out

why does the support button say "contact us" and then brings us to a forum. 24/7 help, but how long do I sit here waiting?? 

I put my jotform link in my IG profile and when you get to the end to upload a photo, the whole screen X's out. I don't wanna waste people's time filling the whole form out for that to happen to them. 

We are sorry for the inconvenience this may have caused.

I cloned your form and tested a submission, but I can't seem to replicate the issue.

May we know what browser you were using when the issue happened?

Thank you.
