Inquiry Regarding Proposal Visibility and Response Status

[#1]

Hi,
I am reaching out to express a concern regarding my recent bidding activity. Over the past month, I have consistently placed bids on client projects promptly; however, I have not received any responses nor seen any indication that my proposals have been viewed. Are there any updates or changes regarding the proposal submission process?
