I have been using Opera for a long time but never expected this.
It's quite dissatisfying and unexpected that in the new update of Opera mini fast Android web browser, the browser language choice for Indic language "Odia" (ଓଡିଆ), which is spoken by almost 40 million people, has been removed.
However in previous versions the Odia language choice was there but in recent update version 23.0.2254.114923 (March 24), it has been removed.
I request you to kindly add "Odia language" (ଓଡିଆ) back to the browser default language choice option.
I had sent numerous feedback and would also suggest you to add Odia as a browser language in PC version of Opera browser.
Expect your reply & prompt response.
