Advice regarding a similar problem on a different thread that might be helpful:

@Rahul-Balaggan said in [PLEASE READ] - Issues after extended Maintenance:

Please go to the account tab of the app. Then in the top right corner there is a sign out button. Please tap that button and then sign back in.

If that does not work, please delete the app and download it again. Let’s know if the issue continues from there.

@GeorgeMTO said in The Frontier Lord Begins with Zero Subjects LN vol 6 part 5 is loading a black screen an the part selection menu is loading everything as default title.:

@heimdal7 should be fixed now, didn't load for me before but does now (got reported on discord and staff responded)

When you have a part opened the drop down menu to choose parts for the other volumes still listed as "default title (short)" for all other volumes.

The issue has been resolved!

Many thanks!

@Calvinabram

Please go to the third tab in the app. The top right corner has a log out icon. Please log out and back in.

That typically fixes it. If that doesn’t work delete the app and redownload it.

Also it's possible your purchase happened during the current "site down for maintenance" situation; JNC may not be processing such just now.

I could be completely wrong concerning there being a connection, but the timing seemed relevant.

It's possible the website is using offline data storage to store the content it downloads rather than depending on the browser cache. Probably too late to test it now but if it happens again I would try clearing that in addition to the cache (in Firefox it's separate but in the same place where you clear cookies).

It was corrected a few minutes ago.

@Salkeaner we've released a new version of the app that addresses issues with in-app purchases

@smiddy1982 email support@j-novel.com ; this isn't something they can handle out in the open, they'll need personal info you shouldn't be broadcasting to look into it.

Since it wasn't stated above

@saffire Thank you! They respond really fast
