Memory Card for EOS M50 Mark II

[Warchild]

Best Buy sucks - neglected to tell me that no card was included - did my best to choose one at Walmart but the camera is unable to format. Gotta shoot a wedding today.

Heere is what the camera manual states:

In addition, be sure to use full-size cards and not microSD cards in an adapter.

I perhaps the card lock enabled?

Learning how to use my new camera while shooting a wedding is not a thing I would want to do.
