We’ll fix it in the next release, so the host can accept query params. Nevertheless,
markread=true is not really required to use OPDS PSE, which we do support.
You only need
markread=true to enable the server-side reading progress sync. That, we do not support. It’s a bit tricky because that feature assumes that every page the app streams should be marked as read. Panels pre-loads the adjacent pages so when you swipe to the next page it’s already loaded.
We might add support for reading progress sync with Komga in the future, but it’s very likely that we won’t do it using the server-side sync, but with their API.
For now, if you only want OPDS PSE, you can simply omit
markread=true and Comics Streaming will be available from your Komga Library.
