Hi Arnold
I'm AnnaThomas and I'd happily help you with your question. In this Forum, we are Microsoft consumers just like yourself.
One possible reason for this issue is that the browsers are blocking third-party cookies, which are required for the authentication of users in your organization. To fix this, you can try the following steps:
In Safari, go to Preferences > Privacy and uncheck the option “Prevent cross-site tracking”.
In Firefox, go to Options > Privacy & Security and select “Standard” or “Custom” under Enhanced Tracking Protection. Make sure that “Cookies” is not checked or that “Cross-site cookies” is selected.
In Edge, go to Settings > Cookies and site permissions > Cookies and site data and turn off the option “Block third-party cookies”.
Alternatively, you can also try using the direct link to your form instead of the embed link. This way, the users will be redirected to the form’s page where they can sign in with their organization credentials.
I hope this helps ;-), let me know if this is contrary to what you need, I would still be helpful to answer more of your questions.
Best Regards,
AnnaThomas
