malformed JWTs on iPhone

[jwldr]

Hello,

I tried different browsers (Safari, Firefox) and the Cloud Personnel Cozy app from the AppStore to connect my iPhone (iPhone 13 with iOS 18.1) with my local cozy-stack (v1.6.31). None of them seem to work, while the access via PC (Linux & Windows with different browsers) has no issues.

It seems that the frontend/js-scripts are generating an invalid/malformed JWT. After providing my instance/user password (when using a browser) or the e-mailed confirmation code (when using the app) I see the following error messages in the log. On the iPhone is just a black screen displayed.

The "Invalid JWT token"-errors keep repeating infinitely until I abort further requests via closing the app or browser tab on the iPhone.
