How to learn to block in Injustice 2?

I went through the tutorials and of course I get how it's done mechanically - though it's a little different than MK series I'm used to, I can't seem to block in time and once an enemy combos starts I'm essentially mincemeat for higher-level players or the AI.
Since blocking involves both crouching and standing, is it just a matter of knowing to the t what other player's combinations are?
In addition, is there a rule of thumb on when to block and when to stop blocking to punish?
I feel like getting this covered would hugely improve my game.
