Look at the bottom of the page. There are 2 icons bottom-right: a sun and a moon. Click on the sun to return to the light theme.

@Rahul-Balaggan Works now. Thank you so much!

@myskaros I'm very thankful that my book is now legible

Thanks @Inuk and @chocolatkey!

I've managed to update my email address, however it's apparently unverified (haven't received a verification email so far and didn't see any messaging about having to verify it after updating it) and I can't use it to log in at the moment. I'll send an email over to support directly, though I figured I should report that issue here as well.

@pcj this worked, thank you!

It is now available. Thank you!

We didn't intend for the forums to open in the app; a future update will redirect forum links to your browser instead.

@chocolatkey I've confirmed that I can now download the volume, thanks for the help!

Sorry about that; this should be fixed now!

It's been fixed. You may cease stockpiling immediately

@myskaros thanks for the fast respond

I'm not sure that's really a bug so much as an expected result.
I suspect that each of those sections is displaying a pointer to the same object, and any manipulation of the object in one area will be echoed within the others.
This would minimize the amount of code required; it's kinda like a subroutine call?
[My last programming class was in 1982, so my grasp of the modern terminology may be somewhat lacking.]

How often one would open more than one of the three possible display areas at the same time would seem a good question, because one would only notice this if one were doing that.
I was able to replicate it within Chrome on a Windows 10 system.
