How to make online reservations to get access to the store?

Only in person.

You have to go to the store location there is no online reservation due to covid 19 .Go to the store at 7am they put out this big QR scan .Scan the QR scan and then it will tell you what time to come in the store .The store doesn't open until 10:00 am

That I don't know so I guess you right

There is a big poster the staff put up next to the line. It has a QR code. Scan it with your camera app, and it will add you to the queue. The checkin system is only available in person.
