When I install the app on my German-language iPad it is displayed in Japanese
When using an iPad set to German (or any foreign language other than English) , LoiLoNote School is displayed in Japanese rather than English.
LoiLoNote School supports Japanese and English language interfaces, so if using your app in German (or any other language setting except Japanese) you can use the app in English.
The iPad's default settings for priority language display are probably German → Japanese → English, so you will need to change the order to German → English → Japanese. To do this, follow the steps below.
1. Select Allgemein → Sprache & Region → iPad Sprache → English
（Your iPad will be displayed in English)
2. Choose General→ Language & Region → iPad Language → Deutsche (German)
3. Launch LoiLoNote School and confirm that it is displayed in English.
