I just had a look and noticed that this feature is missing for me too.

Hi there, Thanks for reaching out about this.

Boost Resolution is still rolling out gradually, so it might not be available to all users with AI features yet. If you had access before but can't access it now, please check to see if you might be using a different account.

Also, we recommend checking back over the next few weeks for updates.

Thanks again for your patience!

I didn't change my account, it's the same one I always used, thanks for your answer Junko anyway.
