Same issue here ! Please HELP
We are showcasing Survey123 to the partner of the company and running the webform in a real project with clients. In the first try to replace the former software (Sphynx) by Survey123 we face this....The company directors cannot submit their forms, that's really frustating.
The submittal is unstable, even all of them having normal internet connection, I could send forms through my mobile phone (accessing the webform via Chrome) and via computer, but my colleagues in other states and our clients cannot submit their answers.
No Error number is presented too:
