Is the new raspberry pi4 compatible with A2 microSD cards?
It depends on what you mean by "compatible". Will an A2 card work? Yes. Will the Pi get the most out of it? No. Will it provide the best performance for price when used in a Pi? No.
It appears that A2 cards rely on specialized hardware in the host device to work at their best. The Pi does not have those features. An A1 card will work pretty much as well in a Pi and is generally much less expensive.
