Hi,
When highlighting multiple words in a sentence there is often quite a slow response time before the translation/audio comes up.
It sometimes happens with individual words too but not as much.
I’m using the desktop version and I didn’t have this issue yesterday.
I am having the same problem on Android. Lessons take a long time to load and the app is lagging as soon as I click on a word. It takes a good 5 seconds for definitions to appear.
