Welcome to the community, @simita! Would you mind advising your team to use modern like Chrome, Firefox, Edge? These modern browsers should minimize many data collection issues, especially when collecting your data through the webform (Enketo). Please also advise the team to update the browsers to it’s latest versions for the best performance.

Thanks the link works now, but we just had to select the option of not requiring authentication.

@simita, thank you for confirming!
