I'm not seeing any pinatas as of today, nor are there any free gauntlets, gems, or coins. I've tried reinstalling the game from a backup, and though my score, etc. is preserved, still no pinatas, gauntlets, gems, or coins.

This is the sort of thing that usually happens when an update is released and the player continues with the old version.
Check to see if the new update is available in your region and decide if you want to update or not (remember the trouble with the last update).
If you do decide to update then take sensible precautions such as taking a screenshot of your streak and player i.d. and having a spare device with pvz2 on it in case it loses your streak data.
As of today the update is still not available to me in the uk.🇬🇧
