Posts not marked as read after viewing media.

Title. I apologize if this is not the appropriate location to report bugs or other issues, or if this has been reported before, or if this is an issue larger than Thunder.

I noticed this morning that despite having it set in settings, opening a post's media will not mark it as read, as it had previous to today. I've switched the settings on/off, restarted the app, restarted my phone, all to no avail.

If I need to report this elsewhere or provide more information, let me know. I went to GitHub originally, but I don't have an account over there, and didn't see an option to report an issue without one.

Thank you in advance.
