My app isn't syncing with the web

Hello. My laptop isn’t working right now, so I imported a pdf into lingq via the lingq website, which was great. However, when I went to the app, I didn’t see the new book. I’ve used the web version on my phone to read it, but the app is better. I uploaded the book on the desktop version of lingq, and then I went to my app, and still the book doesn’t show up. My app also doesn’t indicate that I have a 2 day streak; it says I have a 0 streak.

Please look into this so that I can use the LingQ app.

Thanks for LingQ as well; I’m expecting to use it a lot more this year.
