Hi, I found that there is a issue always happen, when I select some text to translate, it always say `Error: Service usage limit reached. Please wait a while and try again.` even if It's the first time I click translate, when I use debug mode, I find the debug in console says that `statusText: "Service Unavailable"`. This issue would be appear everyday and everytime. BTW, I am using my company's WiFi. (is there any way I can set a additional google api token for myself if this issue is caused by api limit), Thank you!
