Unable to download attachments on Android 10, Librus.

While trying to download the attachment from inbox messages, the following error is occurring:

Kod błędu: 50 (on LibrusSandboxDownloadAttachment) /storage/emulated/0/Download/Szkolny.eu/FILE_NAME:
open failed: ENOENT (No such file or directory)

Does the filename contain any special characters? Does the mentioned directory (not the file, the parent directory) exist?

[gmalinowski]

There are several attachments I think all without special characters like '03.mp3', none of them work. I forgot to add the error title which is Błąd odpowiedzi serwera. Dziennik może być przeciążony lub mieć przerwę techniczną.

And yes, I tried to create the parent directory, it didn't help but the err msg has changed.

[kuba2k2]

Well, then, did you grant storage permissions to the app? Are you using the latest version?

The error title is a generic one, happens for all kinds of exceptions.

[gmalinowski]

Yes, I've the latest version (4.13.6) and of course, I granted the required permissions.

Wow I've solved the problem, kinda. I don't know much about android apps but this is wired. Actually, it has logic in it, the app cannot fetch data from external sources, i guess.

In the advanced settings in app info, it requires to grant permissions to "Install unknown apps" / "Allow from this source". The app was installed from the apk not from the google play. Like on the screenshot below.

Right now, it's downloading the files, but it's still throwing an error:
signal-2023-10-26-144246

After the app restarts everything seems to work just fine.
