Message in Chinese

[KNS]

Perhaps someone else has had this issue.
Whilst attempting a Bluetooth video download, when I select the download button the message in the following attachment appears, and the download fails, even if I select one of the two options. I am using an iPhone 12 and have had no major issues before.

The message is basically saying:
"Your controller isn't connected (to your phone?) and if you switch mode you will lose connection to the drone. Do you wanna continue? No. Yes."

Don't know why it appears in Chinese, could be a bug.
