State your app version and the source, series, and chapter with the problem.
An app update may fix your issue
Wait or check for an app update if you have not already. There are no ETAs for updates.
If you're the only one facing a problem, you might be encountering an IP ban, or other countermeasures set by website owners against programs like Kotatsu.
To minimize future issues:
- Avoid using downloads with the source.
- Reduce the number of series in your favourites/history from that source.
These are general guidelines as each site has its specific undisclosed limits and triggers.
When everyone experiences a problem, it could be with the source or app:
- Check open issues for the app and/or parsers.
- Check closed issues (app/parsers) in case it's resolved but not yet released.
- If not found, create a new issue.
If the site itself is problematic, patience is the only solution until it becomes functional again.
