@RafaelD-5678 Thanks for reaching out and apologies for delay on this. Can you point to the step by step setup you followed for this ?
Did you follow : https://learn.microsoft.com/en-us/azure/active-directory/saas-apps/palo-alto-networks-globalprotect-tutorial or something else ?
If you have setup the SSO correctly, you should not be having multiple MFA prompts, https://learn.microsoft.com/en-us/azure/active-directory/saas-apps/palo-alto-networks-globalprotect-tutorial#configure-azure-ad-sso
You can share us a user information through which We can try to identify and understand why the multiple prompts. You can email us at azcommunity@microsoft.com with subject "Atten-Vipul" and we can get back to you for further details.
