Got my car about the same time as you got yours, windscreen never wiped clear and felt like it had some kind of coating on it already with strange marks and stripes in it. Tried 50/50 meths/water and newspaper scrubbing like crazy, cerum oxide, ipa, acetone but nothing worked.
Ended up using Gtechniq P1 Nano polish meant for paintwork and I could actually see a brownish coating coming off. Went with a desperate view that if I stuffed the glass I’d crack it with a hammer and get it replaced. Then used Gtechniq glass cleaner, final ipa wipe, washed with soapy water then put wipers back. 2 hours hard scrubbing and it now wiped 100% with the wipers. All done by hand with microfibre cloths polishing a small patch at a time.
Then like an idiot I put Gtechniq G1/G2 on it, caused the worst ever wiper judder and had to repeat the whole process to strip that.
So sounds like your screen might have some residue from the factory like mine had which only elbow grease will clear before other coatings can adhere. Leaving mine a week or 3 before applying H2Go as I can’t put myself through that lot for the 3rd time in 2 weeks if it goes wrong
I’m sure other products would do the cleaning quicker and better but I used what I had to hand.
