Additional information
When sending a file with special characters in the filename (especially the hash symbol #) via Nextcloud Talk on Android, tapping the file results in an endless loading state and the file never opens. This issue does not appear on the web version of Nextcloud Talk. It seems the Android app mishandles URL encoding or fragment identifiers when opening attachments.
