Form Limits

Is there a limit to the number of people can complete a form that I have created, at the same time.

As per checking, your account groceriescodeadjudicator is currently on Bronze Plan. Your forms submission limit is 1,000 which means that your forms can accept submission up to 1000 submissions. Your users can access your form at the same time. They can submit the form at the same time as long as your account hasn't reached yet the 1,000 submission limit.
