SUMMARY

On logging in as a domain admin/user, and then logging out, we see an increasing number of requests being sent to the MS, leading to the browser becoming unresponsive. Clearing the cache / opening the UI in incognito didn't help either.
Following exceptions were logged on the MS:

STEPS TO REPRODUCE

1. Login as an admin
2. Create a domain admin and/or a user
3. logout <-- works fine
4. login as domain admin / user 
5.  logout - though logout is successful, notice the devtools network tab - the continuous increase in no. of requests sent to MS which eventually renders the browser unresponsive

EXPECTED RESULTS

Logout as usual

ACTUAL RESULTS

Logs out, but then browser hangs due to increased no. of API calls being made
