Fix BlueMail push notifications on Huawei and Honor

Huawei’s EMUI and HarmonyOS — and Honor’s MagicOS, which grew out of the same code — manage background apps through a single screen called App launch. Automatic management closes BlueMail whenever the system decides it is idle.

Manage BlueMail’s launch manually

Settings → Battery → App launch → BlueMail.

Turn Manage automatically off. Three switches appear; turn all of them on:

• Auto-launch — lets BlueMail start after a reboot.
• Secondary launch — lets it be started by other apps and system events.
• Run in background — the one that actually keeps push alive.

Ignore battery optimisation

Settings → Apps → Apps → ⋮ → Special access → Ignore battery optimisation → BlueMail → Allow.

If mail still arrives late

• Lock BlueMail in Recents (swipe down on its card, or tap the padlock).
• Turn off Power Genie style optimisation by keeping BlueMail in App launch’s manual list — automatic management overrides everything else on this page if you switch it back on.
• Check notifications are allowed in Settings → Notifications → BlueMail.
• On phones without Google Play services, BlueMail must maintain its own connection to your mail server; the App launch settings above are what keep that connection open.
