Has anyone else had this problem? A while ago I purchased both the Flirting, and Esperanto Culture lessons through the shop, and as of today, they seem to have both vanished.
I also checked the shop again, to see if I had to repurchase them, but they're also no longer in the shop.
Yeah it's weird! I'm having the same problem. The fix to getting those lessons was to download the Duolingo app on mobile device. You can also use Microsoft's store to get the Duolingo app.
