I'm experiencing the same problem, but on and off, and across two devices. My first device is a Samsung Galaxy J7 2017, and the OS is Android 8.1.0. Second device is an Asus X502CA laptop, and OS is Windows 10 Home. Edit: Forgot to mention I was using Chrome on both devices.

The game loads to 76% and then stops. I've checked my connection to make sure it wasn't me, and also let the page sit for several minutes to make sure it wasn't just loading slowly. I've refreshed the page, which sometimes fixes it, but not always.

Thanks for looking into this @Mrinja. I've been checking the game throughout the afternoon, and so far there are no problems on my end.

Hello again... reviving the Subject... I am continually getting errors about the game, and it still is saying LOADING 76%. Nothing looks new or changed. I tried to change font settings, see if that had to be the problem. Nothing. The error was just the fact that the number 76% was stuck there the entire school day(I put my iPad away during class switch time)
