Hi

I am having a bit of a problem today with Global Secure Access breaking external sharing links.  I do have tenant restrictions enabled.  

  1. external user sends sharing link to internal user
  2. Internal user clicks link, enters email, and Microsoft emails OTP.  
  3. when GSA client is active, the user is prompted to sign in.  Sign-in blows up, since user isn't a formal guest- they are only being shared a single file.
  4. when GSA client is inactive, the user is immediately routed to the file.  This is the desired behavior.  

I did attempt to add the tenant as allowed in tenant restrictions, and there is no change in behavior. 

  

Any ideas on how to allow this use case? 

PS- I did also open a ticket with my CSP, but I don't generally have success with that route
