Firebase not sending custom APS block

[JakeOrel]

Hey ya'll while working on adding time sensitive notifications to my app it seems the aps block that we are sending to firebase to send to the phone is not getting read/getting overwritten. Ive done a lot of testing on this by filling my Aps block that is sent to firebase to forward with a bunch of random stuff yet it always comes through in the same way. This issue with this is that the interruption-level key seems to be getting dropped and not sent to the app. I was wondering if anyone has ever dealt with this issue before and might have a place to start looking/debugging this. The server is using Java. Thank you in advance!
