There are three possible causes:
If clicking a TOC link causes the target heading to be hidden behind your theme's fixed header, configure the scroll offset setting.
How to fix it:
Open the Settings page in the app
Enter the height of your fixed header (in px) in the "Scroll offset" field(e.g., if the header is 80px tall, enter
80)Click Save
A positive value moves the heading lower on the screen (adding space to account for the header). A negative value moves it higher.
We sincerely apologize — this issue cannot be resolved with the current app specifications.
You will need to either disable lazy loading or accept the scroll position offset as a limitation.
We may be able to help in some cases. Please contact us through the app.
