Often when I search for mails and trigger the server search the results will be shown for a blink/second but then disappaear again afterwards

App

K-9 Mail

App version

9.0

Where did you get the app from?

F-Droid

Android version

Android 15, CalyxOS 6.6.23

Device model

Android 15, CalyxOS 6.6.23

Steps to reproduce

1. Search for sth. in your INBOX. In my case e.g. "ebon".
2. Trigger the online search.

I use Posteo as a mail provider, maybe that is relevant or their server config matters.

Expected behavior

Should find elements and retry search if it fails or whatever. At least not have results appear and disappear.

Actual behavior

It seems to find stuff, even some mails and gets more and more. But often just when I want to open one and tap on it, everything disappears.
That's really a frustrating UX experience and looks even "evil" as it seems to happen just when I've found the correct mail I needed. 😉

Only reproducible sometimes, but I managed to reproduce it multiple times in the logs below.

Interestingly, it seems I got many/frequent connection aborts etc.:

This could be due to the fact that my phone switches between wifi and mobile data or just because the server stops some search requests as I've got quite a full inbox (where searches in their web request even sometimes timeout, depending on the directory). Though I have not searched a big folder there and IIRC the app limits it's search request to the current directory.

I've had this exact issue since long time ago (definitely before the TB move). Also a Posteo user, BTW. Glad that someone bothered to report it properly.

Thanks for reporting! @TwoF1nger do you get similar logs as above?

[TwoF1nger]

I reproduced it on 10.0 today, with another mail provider (via IMAP), but wasn't running logcat. Later, when I tried with logcat, it just won't happen.

This bug usually occurs when I open one of the mails from the search results, delete it, this sends me back to the results list, and then the remote items disappear from the list (but the local ones are still there).

My folders do not have many emails, and my network connectivity is good.

This issue is still present with TfA 16.1
