You only get 60 connects on fresh account.
After that, if you want more, you have to:
-Buy Upwork membership, you pay monthly and get 70 connects per month.
If you don't buy connect, client can still invite you to interview, this cost 0 connect.
This change has been implemented months ago.
THANK YOU SO MUCH!
Just figured out!
Although I have been working on upwork since 2015, I took a break from it for 2 years! Thought it was still working the same way it did back then!
