Experiencing several problems inviting team members to our repository

[Robin]

I made a new project and repository yesterday and tried to invite my team of 4 other people. 
1: Two team members who were using a hotmail.com email account were not able to join because they were not receiving any invitation emails. We have tried resending several times and the emails did also not show up in spam. They opted to make new accounts using a different email provider. 
2: One of the two team members who made a new account was able to join, the other is not able to join because they keep getting an error saying "The owner of this repository (xxxxx) is already at their plan limit and will need to upgrade before adding more users.", even though this is not the case! 

We've opted to wait 24 hours to see if the error persists, and it does. 

What should we do?

Hi @Robin 

I've taken a look at your workspace and can see that you've got 5 users present. Free plans have a maximum user limit of 5 - hence the error that the user received.

You can verify this by navigating to Workspace Settings > Access Management > User Directory and viewing your list of users. A user with any access to private content in your workspace consumes a seat in your Free license.

You'll need to remove a user to make room, or upgrade to a paid Standard/Premium plan to remove this 5 user restriction.

Cheers!
