Yes I have applied for IRCC case notes, waiting for a response from themForeign travel combined with either unemployment or Self-employment is a major red flag unfortunately, as they like to use employment to help verify residency. In the worst case, they will ask for more proof. In most cases, it will just take time. Don't know if this is the cause for your delay, but it is a possibility.
Have you tried applying for case notes from IRCC or CBSA?
