Using firefox 115.10 ESR I notice today
going directly to
https://central.sophos.com/manage/threat-analysis-center/cases (copy that in address bar)
works.
Then clicking on Detections, I get an error bottom right
The detections load after a while regardless the error.
but then If I click cases on the left side or top menu,
cases are no longer working and I'm redirected to the TAC dashboard again instead.
