Hi again!
I was so happy when I thought I had solved everything! But now I realise it’s still a bit of a mess, and I can’t organise my contacts properly.
This is what happens now: When I add a new contact online, it appears twice on my smartphone. However, when I add a new contact to my Fairphone, it syncs properly and only one new contact appears online.
When I delete a contact from my smartphone, it is also deleted online.
However, the opposite doesn’t work: When I delete a contact online, it isn’t deleted on my smartphone.
I also have the problem that there are now many contacts on my smartphone that I can’t delete. They are write-protected — I didn’t intend to protect them and now I can’t delete them. I can only hide them. …
If anyone knows how I can do this, I would be very grateful for any help 
Many thanks!
