I … violently… disagree that this is “extremely confusing”.
You’ve reached the maximum number of likes. Please wait 14 hours before trying again.
What other English words could be used here to make this clear? It seems abundantly clear to me what is happening.
Thanks for sharing the love! You only have a few likes left for today.
The above is an additonal message, a convenience, an early warning which 
indicates you are close to running out of likes for the day so maybe it’s time prioritize the ones you have left rather than scarfing them all down like candy?
All I can think of is
- you used the limit of 50 (or whatever the limit is, it varies by trust level) likes
- you waited 1 hour for UTC 00:00 when daily like limits reset
- obviously this will vary depending on your location and when you use up all the likes. You could use them up 23 hours before UTC 00:00 or you could use 'em all up 1 hour before UTC 00:00
- you then used 50 likes again within one hour, at which point you are waiting for the next UTC 00:00 day for things to reset again
