The A06 is the very budget end of the newer a-series phones, so it probably won't receive the update for at least another month. I have the A16 and I don't have the update yet. You just have to be patient.
You can find estimates online if when the update will be released for your phone, but they are only educated guesses, best to just wait it out and check for updates once or twice a week.
The update is due today according to the Brazil/Global release date list, which has been mostly correct so far, but some phones have got it a few days later than stated.
I wasn't aware of this until now. Although this is probably just the beginning date of the rollout as I have an A16 5g and I still do not have the update.
