If you find any errors please report them here.
That links to the plugin's GitHub. Please do not create issues on Kavita's GitHub for extension-related issues.
First of all make sure Kavita is updated
To make the extension link with your Kavita instance we need the OPDS URL. The steps to get the OPDS URL are:
Access your Kavita instance from your web browser and log in
Once installed the user has access to 3 sources.
This means you can have access to 3 different Kavita servers.
On each source, you can set up different OPDS URLs and different filter preferences.
By default, these are differentiated with a number. 1, 2 and 3.
You can change each identifier with your own.
Follow the same process used for OPDS but tapping "Displayed name for source" instead.
The same process is used for OPDS but tapping "Default filters shown" instead. This will hide or show filters appearing in the filter list. To hide one filter just uncheck the checkbox
Kavita has progress sync with Tachiyomi. It will automatically mark completed volumes and chapters as read in both apps. It does not sync page progress, it only syncs when a volume (or chapter if they are split) is complete.
To activate tracking go to settings > Tracking and click on Kavita at the bottom.
After activating it will appear with the rest of the trackers on your manga page. Make sure it shows its active otherwise it will not sync.
