I changed mine via the heart symbol. Mine was a purple Facebook. So went to the Facebook page and clicked on the heart. There was the option to change it to what I want. The one I really want, even thought it shows blue in the red heart, it comes back as purple.

Now I see Opera VPN is changing all my speed dial like AliExpress to french. Why can't they just leave it alone.

Today I noticed my Google search was in Russian. I turned off VPN and it was back to English. After awhile I turned it back on and again it was in Russian. Guess I will have to turn VPN off until they fix it.
