I've come here via asking a question about the same thing (here). As I note in that question, this appears to be a long-standing issue going back to at least 2016.

My 2c: many small and mid-sized firms engage with external advisors such as accountants. And I suspect that is becoming increasingly common in the aftermath of COVID, in the same way that remote working is increasing.

But precisely because the number of such external users is increasing, what is also increasing is the inconvenience created by not being able to have those external users sync/link to multiple business accounts. For example, the useful functionality inherent in the Groups feature is well-nigh obliterated if you have a situation where you'd really like a Group that contains both internal users and externals.
