How do I give edit access?

I need to share my project with a team of people who will need to be able to edit the project.

I’ve added their email addresses and set their permissions to ‘Edit’. I’ve also updated the link so that anyone with the link can edit.

4 out of 6 people are able to edit, but the other 2 get flagged as having restricted accounts. They’ve requested upgrades as suggested but the requests don’t seem to go to anyone.

What am I doing wrong?

I suggest you contact support directly
