I am new to Upwork, and only had my account approved last week. I was looking through jobs posted, and I have connections available to use, but I cannot Submit propsals. The button to do so is grayed out. Is there something that I am missing?
As an exclusive member of the agency, you won't be able to use your freelancer membership plan/connects. Exclusive agency members can only work on contracts under the agency.
You can find more information about it here.
Please communicate with your agency owner or business manager regarding changing your profile rate above the minimum hourly rate. Once your rate gets updated, you should be able to submit proposals under the agency.
You Agency Owner, or Business Manager can go their Agency Roster (Find Work > Agency Roster), and update their exclusive agency freelancers' profile rates from there. You may read this help article for more information.
