Hi - sadly the reason the web is 50/50 is it depends on how your chain was set up I’m afraid. Adding two more teeth might not be the end of the world as far as your RD is concerned. Last two times I had a shop service my bike though, once the chain was already too short for big/big, and the other it was slightly longer than I needed for big/big. In the latter case adding two teeth (which I’ve done, same as you) was no issue. I couldn’t have done it with the previous setup or the RD would’ve been super stressed. I had just changed the chain and cassette at that point anyway as well, so it meant everything was new/new/new to keep wear in line
Assuming you’re just undoing a quick link and rejoining - just put it on and see what it looks like big to big and take a call.
(Bearing in mind if you’re changing chanrings that were worn, you run the risk of messing with wear everywhere else if the three are too far ‘out of sync’ in terms of wear (the three being cassette, chain, rings))
