No problem, you will do fine with the remote with the software you will have.
People who have MX500s (un-updateable) still have viable remotes. That's one example of a remote that can keep learning new models any time they are introduced. You can learn any new command from any new device well into the future. You are not obsoleted. Any commands not on the remote are often found right on this website. A regular programmer is always on the hunt for some commands that aren't in the database. That's why we ended up here.
I regularly use older MX software versions and program remotes all the time. I am not unable to do new clients' equipment. Anyone who tells you otherwise is not giving you the straight scoop.
It is tiring to read all the scare posts here. I'd sure be grateful if we could move on.
There is no truth anymore. Only assertions. The internet world has no interest in truth, only vindication for preconceived assumptions.
