Can't link invitation as guests to a Personnal office 365 account

Hi,

I am invited to more and more organization as a guests, however I have very hard time correctly linking my account those invitations.

I have a personnal office 365 account "eb@lebrun-burel.com". I can access to the first Teams organization I was invited too with this email.

However, whenever a new organization tries to invite me, I get the screen in the joint screenshot (in French sorry). Basically it asks me to create an account... but surprise, this creates a whole professional account with an organization on my email domain (lebrun-burel.com)!

I've managed to remove this domain and fallback to a "onmicrosoft.com" domain. So now I have 2 accounts:

- a personal one... that is not reckognized anymore in Teams Linux version! It works on mobile, and if I log multiple times it ends up working in the web version. But I am not found in the Linux version, even after a reinstall (my best guest is that now, the app probably looks for me among professional users instead of personal)

- a professional one, in "onmicrosoft.com" that works, but do not includes the first organization I was invited too.

So basically here is my question: how do I tie up additional invites to my personal account, and keep only one account? Only the mobile interface allows an easy switch between orgs.
