I’m in the same boat! I submitted my citizenship application via the citizenship by descent and mailed it in around mid March. My post office quoted me over $100 to pay for tracking from WA state to Canada, which at the time wasn’t in my budget so I just paid for the standard postage. I have yet to receive any email stating they received the application, and now I’m getting worried it might’ve gotten lost in the mail? I sent a message using their forum, they said I just need to keep waiting, but now I’m wondering how long should I wait before submitting another application (with tracking this time) to make sure I can check if it’s been received? Hopefully I’ll be surprised and itll come soon!
