Don't worry! If you previously declined a new student request, you still have the ability to connect with the student. All declined student requests are hidden from view but stay in your records.
Simply enter the student's first name into the search field at the top of your Messages page and click the name of the student in your list to view their initial request within your conversation thread. You now can reply to declined requests as you would normally.
Click Messages and search for the student's first name in the field at the top of your screen. Select the student's message, and reply by typing your message in the empty field at the bottom, then click the icon to send.
Tap the three-bar menu icon in the top left corner of the screen and select "Messages." Tap the search icon in the top right corner. Type in the student's first name and click on their name to view their previous request. Respond as you normally would.
