There’s a new error in the reader for Arabic text. It has started spontaneously deleting all the spacing between words and cramming all the words together. The behavior appears random, and it’s occurring across multiple lessons and courses. It looks like this, and it renders the reader unusable. The source text didn’t have this and the same lessons didn’t have this error until a few days ago. I’ll be working on the same lesson, then look again and it’s wrecked. See here:
Thanks, I reported the issue to our development team.
I’ve noticed the same issue. The Arabic text is randomly losing spaces between words, making it very difficult to read. It wasn’t happening before, so it seems like a recent bug rather than a problem with the original content. Hopefully it gets fixed soon because it seriously impacts the usability of the reader.
Same error in Hebrew 
@chimptastic We pushed a fix for this and it should be fine now on the web. Regarding the app, an update should be released there too.
