Since 5 weeks I’m having this error on my screen when I use Menrise Pro on Iphone IOS 12.0. That appear in prononciation, videos and listening exercises. The other works very well.
I have reinstalled several times the app but it didn’t work. For some courses it works very well and for other it doesn’t. I’m taken all German and some English books.
If someone is having the same bug, might inform us what to do?
