We traced the root cause of this back to a subsupplier issue where some Input Cover parts had a burr in the lattice near the delete key. We’ve since added additional quality checks. If you’re running into this, you can reach out to support to confirm if this is the issue you are seeing and then receive a replacement Input Cover.
Edit to add some clarification that I noted on Reddit: Our quality team was able to root cause this fairly recently, as the failure analysis process spanned multiple suppliers. On the support aspect of it, I’ve informed the team just this morning that we need to update the support flow for contacts where we can determine this was the root cause. It will still take a little time to roll out an updated process.
