Bug: Feeds marking all their entries unread periodically

[foundObjects]

1. Environment

• Device: Galaxy Tab S6 / any
• OS: Android 12 / 10-13 tested
• APP: 0.9.7

2. Describe the bug

Every few days randomly selected feeds are marking all of their entries unread. This is happening on all of my devices (two phones, tablet, two android ereaders) and seems to affect 1-3 feeds at the same time when it occurs. This happens maybe once or twice per week per device.

Bug repro involves just waiting a few days until the bug occurs, there's no obvious rhyme or reason to it. For a couple of weeks now I've just been opening the app, selecting each feed and marking all as read again - but it's now obvious that this is repeat behaviour and isn't resolving itself.

Let me know how I can capture any debug info you need. Some of my devices are rooted, others aren't, and I'm happy to dump anything that'll help with debugging.
