Topic
When Microsoft Defender for Cloud Apps (MCAS) is setup in an Office 365 environment, users are unable to open both Workflows and Forms due to MCAS adding mcas.ms to the URL.
Instructions
Nintex currently does not provide any accreditation or official support for Microsoft Cloud App Security (MCAS).
If MCAS is enabled then kindly disable MCAS as Nintex is not compatible with MCAS.
