Lock screen on S9 keeps reverting to default after a week or so

I've got this awesome little animated lock screen as part of my theme I paid for, and like once a week it resets back to the default infinity theme. Recently I try to reapply the theme through the samsung store and it no longer changes the lock screen. Has anyone else experienced this?

Any theme I've tried out has always held @D4YTONA 

If this was my situation I'd give some feedback to the developer of the theme via the comments / review section of the theme in the theme store and or any other means of communication to the developer.

I too am having the exact same issue.  It's extremely frustrating.
