Yes, but A1 are cheaper and work better apparently.

Instead for A2 go for capacity or better 4K files R/W (Samsung Evo+).

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.

The EVO+ has been replaced by the EVO Plus, which is not as good. SanDIsk Ultra A1 is less expensive and performs better.

No. The A2 cards will function, but performance will be inferior to less expensive A1 cards.
