plywood warps, cups, twists. nature of the beast. it's wood, it reacts to humidity/climate/temperature

for smallish plywood "canvasi" you can try cutting to size, then sealing with poly/lacquer.
that'll likely help in about 50% of cases.

consider MDF - much more stable, especially when sealed. or, plywood full contact surface glued to MDF.

I'm not a painter, but when I was a kid and wanted to try to paint with oils, my parents gave me 1/4" Masonite. It's not plywood, but it's kind of like wood. Sort of.
