"Now that the BULK January update is rolling to more countries."
Which S21 models and countries have a BULK update? 😉
"It's BULF . Uk and Bangladesh are receiving as far as I know ."
That's correct. BULF is the latest update being rolled out to the international, G99*B, models, currently.
It is highly unlikely that there will ever be a BULK update for the international models as we are now in 2022 and will be seeing CVA* updates.
