Stars not accumulating in AlphaBetty characters

Thanks, I’ll try that on those two artifacts. My more recent artifacts are also not accumulating stars even when I’m earning 3 stars either though. The ones that hadn’t ranked up all the way were all accumulating stars up until a few weeks ago. Since then, they are frozen. I’m wondering if deleting the app and reinstalling it may help. I’ve had this app on this particular device for a few years so I don’t know why my artifacts are suddenly frozen. I have all of the artifacts up to Traditional Betty. Are there more after that?

So earning stars on levels above 365 does not have an effect on artifacts currently available?

Thanks abe_coffee that answered my question. I appreciate your help.
