Feedback: packs from herrprofessor.com not working

Hello Sir/Madam,

I am German studying student from www.herrprofessor.com online course. I have been using MemRise regularly. But from last few days the MemRise packs from www.herrprofessor.com is not getting loded. The app opens bit hangs just showing MemRise. I tried clearing phone memory, logout and login, phone reset and even tried on another device. But none of them could solve the problem. One more student from this community also is also facing simmilar issues.

I request you to check and rectify any problem in the App.

Thanks
Mahesh
