Maybe try using a VPN. It worked when I used a one plus two and wanted a update. Check and see were your model is being updated on the Nokia community forum. It's worth a shot I suppose.
Ive just picked up my Pre-owned yet BNIB 7Plus from CEX... and I was surprised to see its still on August 2018 security and 801, yet my Xperia xz2 has been on P for about 2 weeks now... but at least Android P is rolling out now, so all we have to do is wait
Im no stranger to manually flashing Roms and I know its on XDA but Ive just unboxed this phone and I dont want to start flashing it, Installing Android tools everywhere.. Ill just wait and enjoy it first
Another wee has gone by and HMD Nokia has still not delivered either security patches (still on the August one) or Pie to the Nokia 7 Plus TA-1055 00ww-2-22m build in the UK.
Bad support from HMD Nokia for this product in the UK.:'(
