Missing PCS cookies from the request even with ADP disabled prior to ever using Rclone

Suspected Bug

What is the problem you are having with rclone?

Hello to everyone! Excited to being a newbie to this technology. Using the command rclone ls remote: returns the HTTP error 423. I already was aware of this while setting up my remote, and had read the threads about it, but when checking the ADP, it was already OFF. Apparently I had it like that before. Also iCloud via web is on. But I still get the error. I checked both iPhones and the Mac, they all show ADP OFF, web access ON. I should say that I’m using version1.72 (built with GO from GitHub) because 1.69 (with curl) would not pass the initial config phase.

Run the command 'rclone version' and share the full output of the command.

- os/version: darwin 15.7.1 (64 bit)
- os/kernel: 24.6.0 (arm64)
- os/type: darwin
- os/arch: arm64 (ARMv8 compatible)
- go/version: go1.25.3
- go/linking: dynamic
- go/tags: none```

Which cloud storage system are you using? (eg Google Drive)
