I tried to use the Styles section to copy the basic colors from the previous version but it seems like the styles doesn't work. I had added the new update but because Styles section wouldn't work I couldn't duplicate background colors, font and button colors etc so I stayed with the old version
You do not need to add the new update. Simple: delete the old version .. and import the new version. If you have made major changes -> export the MIX and send it to us. We will see... how we can help you! Thanks!
