I heard about this issue, and sure enough, my two boxes (with expiry dates 2027) have no notch codes. Luckily, I could tell by touch, which side was which... That's just dumb, MACO. Dumb!
I cheat and use IR "goggles" the emulsion side shows bright white with the goggles. Still I use the notch to orient the sheet.
That's shocking to hear, hopefully just a limited amount.
When i complained to Maco about my last box of Rollei IR400 having no notch codes, their explanation was "it was not possible to punch the notch during the last production run. However, there should have been a sticker on the packaging indicating this."
Touch with moist lip both sides...if it sticks THATS the emulsion
(well it worked with the old 1/4 plate glass plates I used to use - donkeys years ago) ....worth a try.

I guess I lucked out, my box has notches.
I have a set of NightFox Swift NVG, but I'm reluctant to use them with IR film since the IR emitter glows a very faint red.
