Troubleshoot missing threads

There are several reasons a thread may not appear in your Shortwave inbox. Here’s how to troubleshoot and fix these cases:

Settings affecting inbox threads

• You have a "Skip inbox" rule set up in Gmail > Settings > Filters and Blocked Addresses
• You have a "Deliver never" schedule set up in Shortwave > Settings > Inbox
• You blocked the sender of the thread in Shortwave > Settings > Blocked senders
• You’re seeing messages that have been resurfaced with Gmail Nudges. You can turn these off from Gmail > Settings > General > Nudges.

Slow sync during bulk operations and email imports

There are times where Shortwave needs to sync large amounts of data with Gmail, causing the Shortwave inbox to be slow to update. This can happen during initial import immediately after signing up, historic import after upgrading, or during a large bulk action. This is just a temporary disruption as the sync completes. It can take days to finish syncing in the very worst of cases, but your Shortwave inbox will eventually catch back up to Gmail and sync in near real-time.

Trash & Spam

Messages trashed or marked as spam do not show up in Shortwave. You will have to view these threads back in Gmail. Untrashing or reporting them as "not spam" from Gmail will bring them back to your Shortwave inbox.
