Hi: I am new to Upwork and am currently very busy with non-Upwork client assignments. In addition, my Profile is not completed to my satisfaction. My profile status shows "Available". I have not had time to check job posts and I am not comfortable submitting a proposal unless I can dedicate time to it if accepted. Should I change my status to "Not Available"? If I become available prior to the date showing on my Profile, it is OK to change the status back early?
