Unsubscribe/Unsubscribe preferences links still doesn't work in your emails.
It is working for me. What happens when you click on the unsubscribe preferences?
Nothing happens, no click is registered. I thought this could be an issue on my end, so I tried unsubscribing from other newsletter, there it worked fine.
For Leet it troubleshooting purposes, I use protonmail and accessing it via mask browser on android device running android 13.
