One option disappears on Android tablet
We have built a web course in AS2. When published in an LMS it works fine on a PC, but when we are doing a quiz on a Samsung Galaxy Tablet (os: Android) one option (the last one) disappears in the Sequence Drag-and-Drop question. The option is still there but the text disappears but when clicked it reappears. I hav eno idea why this happens.
We use Google Chrome as browser.
I attach a video of it since it is a bit hard to explain.
