I'm studying a course remotely, and sent my teacher a message on Teams about 10 days ago now, asking a question. No response, but I can see the read receipt. Hoping to prompt a reply, I asked another unrelated question three days ago. Still no response, but this message has also been read. It's been in my teacher's work hours, and I know that they've seen the message, and haven't been on holiday or out of office.
The questions aren't vitally important, or I would have chased them up earlier, but I'm not convinced that 10 days is an appropriate amount of time to be waiting for a response to a very small question - especially as my teacher has explicitly said that we can contact them on Teams if we have any questions. So it's not as though that form of communication is out of bounds.
I'm in this course for two more years and want to keep things polite and professional, and would appreciate any advice on the best manner in which to chase this up, or prompt my teacher for a response.
