The overall experience on managing contacts on proton has become really bad.

You cannot create groups, meaning list of contacts, from csv, so if you make a contact list of 80 people for work, you have to add all them manually to a group. If you have multiple groups to create it quickly becomes a nightmare. If you send an email to a group, it does not save ?? So if you want to prove an email has been sent or reuse it, well you cannot, you either make screenshots or external records to proton, or you have nothing
.
I do not understant why business accounts have such limited options, but as someone on a visionnary account, I am thinking on leaving proton altogether because I no longer have the patience to do everything manually. Actually I have rarely create groups and used other platforms because of it.

On top of that, managing the groups once it's created is really bad : it does not detect doubles, you cannot modify badly typed emails. There are no subgroups, and the contact window is extremely narrow instead of being a full page. It is neither accessible nor nice to use. Being stuck to do everything on a tiny portion of the screens make zero sense. And the worst part is that plenty of times, the tiny contacts button simply does not appear, and there are no other ways to open the tiny contact window. There a no links to contacts in the left panel or anywhere. In the mobile app it's completely at the bottom and limited. I do not understand.

So an email app makes it really difficult to reach and manages our contacts. I am starting to wonder what is the poin.. I just had a horrible time managing a group and I am weighting my options.

The contacts are so neglected that there are no "Proton Contacts" app.

Please consider changing the core of what is used in an emailing service.
