I am also having this problem on my iPad Air 3, OS: 15.4.1
From what I can tell (I'm not a mobile developer), it appears to be a memory problem. Below are the memory usage I recorded when opening the Bookworm manga page, using the Xcode Instruments and the web inspector.
iPad (Portrait): 1.8GB -> 3.6GB!! -> 2.5GB
iPad (Landscape): 1.5GB -> 2.6GB
iPhone: 2.3GB -> 2.6GB
iPad (Portrait): At least 600MB before it crashes
iPad (Landscape): 497MB (max), 434MB
iPhone (Portrait): 319MB (max), 210MB
Macbook: 741MB (max), 681MB
No relevant errors could be found on the safari console.
That’s a real bummer. I literally only bought my sub so I could read this novel, gonna have to cancel now unfortunately since I was literally in the middle of part 4 vol 3 and now I can’t finish them! Was a great novel too~
again, nowadays you can buy the books even without subscription
but the subscription helps you keep up with the series and is cheap enough to maintain (I'm Mexsican, Cheap is what
I seek the most)
Is buying the epub the same as reading the pre-pub?
I assumed that they weren't connected. So in order to read the book you purchased, you have to download the epub file and open it with an appropriate digital reader.
If you buy the premium e-book you get permanent access to the pre-pubs for the associated volume. Though do note that if you want to read the final retail release with any bonuses/corrections you do need to download the ebook and use your preferred reader.
I think that error may mean that it's a problem with 3D secure which JNC currently doesn't use (it's on their to do list). I'm not sure anything can be done if that's the issue at least until the payment part of the site gets updated.
Most of the time all I get is the generic "thanks for submitting this, we'll forward it to the appropriate translation team" thing.
But there was one time where they really did disagree with my suggestion, and emailed back concerning why they disagreed concerning it being in error.
It was a really weird section of text in how it could be interpreted, whether it was spoken aloud or a mental thought to self, and that was made worse by the title of a book showing up as part of it; book titles go in italics, and if it was spoken that's how it should display, and if a mental think... it was a truly weird formatting issue, to put it mildly.
But they discussed it with me.
They disagreed, and still disagreed at the end of it all, but they didn't round file it when they decided they disagreed, they informed me as to why they weren't in agreement.
That impressed me.
These days, my submissions tend to be screen prints with highlighted text and text boxes explain what I see as the problem.
