@ikeya23 Hi Serhankalay, I think the issue could be due to incorrect file headers or MIME types being sent by the server. Make sure the server is correctly configured to send the appropriate MIME types for Excel and PDF files to ensure proper interpretation by the browser. Furthermore, check if there are any server-side scripts or configurations altering the file types during the download process.

On the computer everything is downloaded correctly, in the browser on the phone everything is downloaded correctly, all extensions are set correctly. The problem is with the Website 2 APK Builder application, only it is downloaded with the .bin extension

the same problem
