This is an issue on the Memrise course Korean 1. I completed Lessons 1-11 and the majority of the lesson 12 (3 new words remaining) in the App on an Android device. However, when I try to continue lesson 12 by pressing “Words and Phrases” it says “Error: Sorry there was an error loading the session!” leaving me unable to continue lesson 12. This has only been an issue for lesson 12 though, because I have since been able to complete the rest of the course (in the App on the same device). I tried reinstalling the app but that didn’t fix it. I have also tried completing it online with a MacBook in a Safari browser and I see the same error.
