Unigram Mobile 26.8.6012.2

Summary

Restores Live Tile content and repairs the Windows 10 Mobile background notification pipeline, adds resilient WNS/TDLib registration and privacy-safe diagnostics, and supplies a signed ARM sideload package.

Live Tiles

• Restored latest-chat message, sender/group name, and available chat icon.
• Removed startup behavior that cleared the Live Tile.
• Allowed tile updates for inactive accounts when notifications arrive.
• Preserved badge updates separately.
• Added XML escaping for notification content.

Push and background notifications

• Restored Unigram.Native.Tasks and the out-of-process raw-push handler.
• Corrected PushNotificationTrigger registration and manifest/native entry-point wiring.
• Removed stale/duplicate tasks and added background-access handling.
• Guaranteed background deferral completion.
• Restored native toast, badge, and tile processing while suspended.

WNS/TDLib

• Retries registration after authorization/user-ID readiness.
• Re-registers channels instead of blindly trusting persisted tokens.
• Fixed multi-account receiver mappings and stale mapping cleanup.
• Fixed TDLib error 400 caused by zero-valued secondary account IDs.
• Deduplicates IDs and rate-limits retries.

Diagnostics

• Added persistent privacy-safe push diagnostics and export from the hidden Diagnostics page.
• Records background access, task/channel registration, sanitized TDLib results, native activation, raw-push receipt, and tile updates.
• Fixed early-startup diagnostics crash and added rolling log limits.
