Left beta testing program, but think beta is still being installed on phone

[silverfang77]

I just left the beta testing program because I just don't have the patience to put up with all the problems entailed with it. However, when I reinstalled FB on my Galaxy Edge from the Play Store and checked the version number in the App manager, it said I was at version 50. Is this a beta version or the current version for phones? My tablet's Facebook is at version 43, but this may be different because it's the tablet app.

Thank you.
