Popup message and Text customization issue after upgrade

I think it’s a little different from the one in the link you mentioned. You see the problem if your default locale is not english and if you change “chat dm retention days” 0 to x days .
Also, the solution you mentioned doesn’t work , you can not change the text (js.chat.retention_reminders.dm) even in safe mode. There’s 500 Error when you try to change.
