It’s definately in the help tab and then backups... it will display a list of downloads and uploads. When you connect initially it should download a copy, or you can hit download the settings to save a copy before changes are made. Then after changes, upload settings, and it should save a copy too. Be aware with simply the the default reset button it may restore settings but for wrong configuration (3s, 4s). You will know this as suddenly your battery percentage is way way down. I just use the help tab then backup list.

It's probably because you are using Ni80 (alone) which is a "non-temp sensing coil." It shouldn't even let you enable a coil that is not compatible under the replay profile (no save puff in box). It has to do with the TCR since this is what's needed to correlate the increase in resistance with other parameters.

I have obsereved the same, the cycling maybe the intent...manual says “charging starts and stops automatically and OTG charging will not over-drain the dna250c.”

As soon as I saw this I ordered since I wanted that version paranormal from a reputable US vendor, in stock, and non-preorder. Thank you subohm. https://www.vapordna.com/Lost-Vape-Paranormal-Dual-18650-DNA-250C-Box-Mod-p/lvp250.htm VaporDNA (CA), Elementvape (CA), & Eciggity (HI), were the three US based vendors I was watching (that had stock) and they all sold out extreamly fast!

Same as op I am also in the US and am surprised there are not more US vendors offering preorder as one UK site says available as of 3/30 already. UK one: https://steamisland.com/collections/side-bar-brands/products/paranormal-dna250c-by-lost-vape
