Sadly, millions.
Spotting is not a reason to be asked to stop hormone therapy cold turkey.
If there is any concern this should be investigated whilst continuing your treatment, and the hormone therapy tweaked as needed to hopefully eliminate it.
Spotting can also result from vaginal atrophy, so an examination should have been offered for this and appropriate treatment initiated.
There is never any justification for withdrawing someone's hormone therapy without proactively providing vaginal estrogen, particularly since it sounds like you have a history of GSM anyway.
I would go back and insist that these issues be addressed.
