You can claim your 7th day of research, get the 7th day stamp, but as long as you DON'T TOUCH THE BOX, DO NOT OPEN THE BOX, then the legendary will stay undetermined. Once you open the box the legendary is set.Bit of a weird/dumb question: if I skip a day and don't do a research task thus breaking my streak, does it reset the counter or not (i.e. do I have to start from 0 days)?
Asking because Articuno comes out tomorrow but today is my 7th day. The impatient me is saying wait for Articuno (because I don't have one yet) but the OCD me is saying keep the streak alive.
Get 7th day
"Claim reward"=open box, legendary is set here

Afaik you can only "save" two unopened boxes, so you can't get to july and claim 8 of whatever that month is
