Some of the other issues with iNat data import to iRecord are highlighted in these posts:

From reading through those, my understanding is that most issues seem to be on iRecord’s end, with misunderstandings/unrealistic expectations for how iNat data works, weird importing of iNat data, or needing full legal names for data (not going to happen for most users with iNat). I’m sure some users may voluntarily do this, but there are plenty of good reasons to not use one’s legal name as a username online. Even changing a username comes with a bit of a cost as other users may not recognize the same user with a new name.
