Why am I not allowed to add any more clients?
updated 2 months ago
You can't add more clients because you've already used the full amount of clients that your account plan allows you to have.
If you want to have more clients, you have to upgrade your account to a Pro account.
On the Solo account you can manage up to 35 clients and on the Pro account you can have unlimited clients.
You can read here how to upgrade your account.
