App

Thunderbird for Android

App version

18.0

Where did you get the app from?

F-Droid

Android version

16

Device model

Pixel 8

Steps to reproduce
  1. Buy Eiffel Tower tickets.
  2. Wait to receive the tickets. Confirm with the Gmail app or Thunderbird desktop.
  3. Observe that they're not shown at all, neither in the inbox nor in "All Mail" in Thunderbird.

Alternately, you can try loading up this email (replacing the redacted parts) and sending it to an email address and testing it there.

Billet Tour Eiffel - Commande ID_ 262010284607 - 'Billeterie Tour Eiffel' (serviceclients@toureiffel.paris) - 2026-05-11 1730.eml

Expected behavior

The email should be shown.

Actual behavior

The email is simply missing in the inbox or any folders, as if it never arrived. Other emails, like payment confirmation, arrived properly. Refreshing doesn't help.
