Hi Annie,
Your timeline sounds very similar to mine—we haven’t had any updates since February either. I submitted a webform and was told the file is currently being processed in POS. I followed up with POS directly, but their response only confirmed that applications are still in the queue for review.
If it brings you peace of mind, I’d recommend sending the webform, though I’d manage expectations as the information you receive may be quite limited.
Wishing you all the best and hoping we both get updates soon!
