Earlier quoted context omitted.
German speakers usually have very good English, but this is one of their tells.
Another one I've noticed is using "I've" as a contraction in e.g. "I've a meeting to attend". Seems totally reasonable but for some reason native speakers just don't use it that way.
As in “I’ve done it” or “I’ve seen it”
It would not be used before a noun, in the context of ownership, as in “I have a meeting”
