Drawings get reissued. The one you are building from has to be the one that is currently authorised, not the one you happen to have.
Being fluent in a superseded drawing is worse than being slow on the current one. You will work quickly and confidently, and produce the previous version of the job.
Put Rev A and Rev B side by side and the differences are clouded on the sheet -- that is what the clouds are for. Two devices moved. Somebody who kept working from Rev A installs them where Rev A said, accurately, and then does it again in the right place after it is found.
Check yourself: You have a photo of the drawing on your phone from last week. Build from it?
Answer: No. Do not build from an old screenshot when a revised sheet has been issued.
A screenshot records what the drawing said when it was taken. It cannot tell you whether it has been reissued since, and it will keep looking authoritative forever.
