Hi, I don't remember exactly from which release it started, but for a couple of months, quick filtering has not been working properly. For example, when typing the sender's name, the results show emails from other senders, and the sought name can be found in the 'Copy' field or in the message text. However, quick filtering works as before, fully correctly in Troubleshooting mode 😳 Attached screenshots with quick filtering results shown when opening TB in 'Normal' and in Troubleshooting mode.
