We had an issue between 10:20 am and 12:33 am on our plateform. All contact elements (buttons, invitations, chat box, call box, ...) were displayed in English instead of configured languages in your iAdvize account (French, German, Spanish...) .
Our technical team has identified and developed a quick fix to mitigate this incident. You shouln't have this problem right now.
A new fix will be deploy in our next release in order to close and prevent this issue in the futur.
