It works for me

Hello all,

I hope you can help, I use the latest version of Opera Mobile for Android (Android 8.1).
When I have to upload a file on a website (any website) I click on the link or the button to select the file to upload, a popup are opening to select the file, but I can't select the folder where my file is because I can't browse my disk, there is only 3 possibility to choose video, camera and contact (!)... Please, how I can browse my disk to select my file ?

Thank you for any help.
