I discovered this when playing with some NFC tags on a Samsung S10E. In short, a simple unlocked NFC tag containing a youtube link was scanned with the app a few times. when trying to clear them, they didn't seem to clear.

  1. download the NFC tools app
  2. write a youtube link to an NFC tag (i don't have the tag with me right now but it seemed to be a fairly basic ISO type tag as shown by nfc tools)
  3. scan the tag with this NFC reader app (v0.15) one or a few times
  4. click the "clear all" button

Expected Behavior: the youtube links scanned from the tag should disappear from the app Actual Behavior: They do not disappear from the app

Apologies in advance for the lack of some details. Its also entirely possible that this might be user error so don't sweat it too much if its not reproducible

I fixed this issue in my fork: https://github.com/mueller-ma/NFCReader

Currently you can only download it from GitHub, but it should be on F-Droid soon.

This seems to no longer be an issue on my device, although i tried it with other NFC devices that i had on me (basically my wallet) so maybe its not a perfect test
