● I accidentally switched the UI of WorldPenScan WiFi to a language that I cannot understand, how can I switch it back?

Please swipe from right to left on the screen of WorldPenScan WiFi, and click the "gear" icon to enter the settings.

Then click the item with a blue [planet] icon to enter the interface language setting list.

Refer to the image below to know which language these unrecognizable languages correspond to from top to bottom, and select the item you want to use to make the pen scanner back to normal.
