JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Apologies for the inconvenience. There was an attack in our servers earlier but our backend team has fixed it as quickly as possible.
I checked your form URL in different mobile browsers, and it seems to be working properly. Here are the screenshots:
1. Android KitKat on Chrome
2. Safari browser on iPad Air emulator
3. Safari browser on iPhone 6 emulator.
Let us know if you are still experiencing problems on this. May we also know if the form is embedded on a website?
