text: Unfortunately, this is a very serious complication that stops me from using my ledger as a two-factor authorization device. If I forget to reset before flashing, I will have problems regaining access. And if I too often do a reset, this may look suspicious from the point of view of the site, and I try to avoid too close attention to security issues. The idea is good, the implementation is poor.
  The only thing I could find was this reddit post, saying that the counter problem will be fixed soon.
  That's why I removed the warning from the start post and expect that the Ledger Nano S can now finally be used as a FIDO U2F device without any counter problem.
