They are advancing quite a bit, actually when looking over the BBC and institute of war maps. Just chugging and grinding along, and now the northern side is beginning again. Drones may help, but they aren't going to stop it.

Russia isn't advancing at a pace that allows them to actually win the war by capturing territory alone. Hence their efforts to crush the Ukrainian economy (and spirit) with endless attacks on Ukrainian civilians. That is much more concerning than the small amount of territory Russia is taking.
Ukraine is taking territory as well where it can with minimal casualties.
