"Connect with a list of LinkedIn contacts" - Only 40% of contacts from list added

Description of the issue:

For example: I tried to run a “Connect with a list of linkedIn contacts” automation, I copied 10 linkedin URLs as described in the playbook Manual (Connect with a list of LinkedIn contacts)

however, when I checked afterwards, only 4/10 linkedIn contacts were on “pending”, meaning only 4/10 connect requests were actually sent out. I previously had tried with a list of 20 contacts and had similar results. How can I run the playbook so that all contacts in my listed get a connect request?

I created a Loom Recording for the Issue here:

Thanks in advance.
