I was in an online match when this happened. I, playing plants, was at 13 health with 7 out of 8 shield squares which guarantees a block on the next attack. The zombies had a strike through hotdog. When it attacked, the shield meter filled up but no damage was blocked. At this point I had a full shield meter with 11 health. The next attacked was a garguantar that did 6 damage, no shield block. Lastly, another garganuar finished me off doing 5 damage, no shield block. I took 13 damage this round and lost a game that I could have easily won. The entire time I had a full shield meter.

You can't block with a full hand, so if you have 10 cards, it doesn't work.
