When you say application fees are you referring to application fees with AADSAS? If so, then cashing a check just may take some time because of the vast amount of paperwork they have. Hopefully, it will be cashed soon and mailed out.
Ya just have some patience. It took an entire week for one of the schools to cash in my check, and it's not even updated on my AADSAS or anything. I didn't even get an email about it. I only know cuz I checked my bank account. lol
