FAQ
Zairyuu stopped working
If you do not use it for a while, you have to log in again. Please do steps 7 to 10 of Part 2 again (tap「連携」and enter your email address and authentication code). The authentication code does not change. Use the one you received at the beginning.
I cannot find the email

I want to do this on a computer
The Claude desktop app on a computer stops partway through. Please use a smartphone.
The connector shows 「連携」 (Connect)

I cannot find 「カスタムコネクタを追加」 (Add custom connector)
Please update the Claude app to the latest version. Open Claude in the App Store (or Google Play) and tap "Update" if it is there.
