VA timelines

I have a few requests in with the VA and wondering how long these normally take to process.

1. Request for a copy of my military medical records. I moved several times and couldn’t find my hard copies. My request for copies of this went into the VA about 18 months ago.
2. Adding dependents. I input my request to add dependents occurred about 6 months ago. It has disappeared from the listing in my VA login as items I’ve requested, but no updates or correspondence on this whatsoever.
