Yes.

We tested zaps and zap receipts on this note… we made seven attempts to⚡zap this note, at ryand@getalby.com, over a period of about 8 hours. Six of the zaps were successfully paid, meaning you should have received a total of six satoshis over this time. However, we did find that only one of the payments produced zap receipts. Why does this matter? Basically, when your side fails to send a zap receipt, the zapping user would not see an actived ⚡icon after zapping. This means they might think the zap failed, and therefore might not zap you again. This is not ideal behavior. You might want to think about switching to an always-on lightning node, to receive zaps.
