@LA20000 @MandyHiman I bought a few chapters to test, and the script seems to work just fine (even for the more expensive, latest episodes). Please double-check that your script is logging in correctly. It should say something like:

...
LOGIN SUCCESS
<RequestsCookieJar[<Cookie glsc=<SECRETCOOKIEHERE> for pocket.shonenmagazine.com/>]>
Getting from URL: <urlhere>
...

If you've bought the chapter, the script logs in correctly, and it still fails to download, you can see what it says if you add print('data:' + json.dumps(data)) to line 163. Here:

        if pageStructure == None:
            print('Could not download pages. Most likely this volume is not public.')
+           print('data:' + json.dumps(data))
            sys.exit(1)

For me, it has "hasPurchased": false and "isPublic": false for chapters that I have not bought.
