well, i just clicked to install the new update for XD and surprise, it started in Japanese even when my main language is already set up for Spanish.
already uninstalled and reainstalled but the issue persist.
Are you using Windows 10? In this case please go to Region and Language Settings (open it by typing language in your Windows application menu). There you have a list of languages, they should be sorted as a priority list of your preferred languages. Spanish probably is the first in your list but it is not supported yet by XD. Probably the first supported language in your list is Japanese. Please make sure that the second language in your list is English (if this is the language you'd like to have for XD). We also support French, Deutch and Korean for the moment.
Please tell us if your problem is fixed.
thanks! my English is better than my Japanese so this is a fix for me.
