It would be highly beneficial to at least have the option to choose the language of the warning or configure it. Construct 3 is used worldwide, not just in English-speaking countries, and many users may not understand the current message.
One possible reason someone might still be using outdated browser versions is that they are installed on government-provided devices, such as interactive whiteboards in public institutions used by thousands of teachers. These devices are typically not managed by the end user, making updates and modernization significantly more challenging.
If that is the case, and upgrading them is not a feasible option, I understand that there may be no solution for these specific devices under the current Construct 3 requirements.
Thank you nonetheless for the clarification and for the great work you do.
Best regards.
