In my opinion, it may be coincidence, because improvement after long-undiagnosed deficiency often is a process during which symptoms worsen and wane while there is a pattern of overall improvement.

If that is not the case, you would be very unusual. There are many variables, so I would suggest you do whatever seems to work for you. I doubt very much that the cyanocobalamin can be a catalyst. It is not even usable until your body converts it to a lesser amount of the usable form.
