Library updates

1. Open Settings › Library updates.
2. Under Schedule, set Automatic updates to how often to check. It is Off at first.
3. Android Automatic updates device restrictions picks when checks may run: Only on Wi-Fi, Only on unmetered network, or When charging. Only on Wi-Fi is on from the start.

The top of the screen says when the next check runs and how many titles it will look at.

These settings, and the rules below, belong to the profile you're in. Each profile checks on its own schedule and gets its own update notifications; archived profiles aren't checked.

Every check follows the library's rules, set on the same screen:

• Categories and Sources turn whole categories or sources off.
• Types leaves out comics, video or books, once your library holds more than one kind.
• Skip an entry when… skips titles that are completed, that you haven't started, or that still have unseen items. It can also check a title only around when its next release is expected. Skipping completed titles and checking near the release are on from the start.

Select a category to give it its own Skip an entry when… rules and Check every schedule; turning Use library rules back on drops them.

To set a different rule for one title, select the updates button on its page, labelled with the expected release, such as 3 days, or the title's state, such as Paused. Choose Always check or Never check, or for several titles at once, select them in the library and choose More › Update mode…. Follow library rules puts it back. The same sheet says why the title was or wasn't checked.

Select Last update in Settings › Library updates, or the time at the top of Updates, for the Update report. It lists what failed, what was new, and what was skipped, and lets you retry failed titles or move them to another source.

With sync on, Last update shows the latest update from any of your devices and names the device that ran it. Its report gives that update's counts, while each title's result stays on that device. Last update here under On this device opens this device's own report.

Pause source leaves a failing source out of updates for a day, three days, a week, until a date and time you pick, or until you resume it. Select it again to resume.

Checking or downloading a lot from one source at once looks like an attack to many sites, and they answer by slowing down or blocking requests, sometimes for everyone using the source. Katari warns when one update checks more than 60 titles from a source, or when many comic downloads from one source queue up.

• Split your library into categories and turn off the ones you don't follow closely.
• Leave Only check near its expected release on.
• Download a few chapters at a time rather than whole series.
