Hi everyone,
Long time lurker. Figured I'd put my info in the queue to help gauge timelines

I actually submitted my online application and paid my fee in March 2019, but I didn't get around to submitting my docs until December 2019. I attached an explanation letter with my documents to clarify that none of the information had changed since my online application, and it hasn't seemed to cause any issues yet.
Application submitted online: March 2019
Documents sent by mail: 04 December 2019
Email acknowledging receipt of documentation: 07 January 2020
Confirmation of address email: pending
Date added to FBR: pending
Congrats email: pending
FBR certificate received: pending
Fingers crossed for spring/summer 2021!
