Hi all, thanks for the additional info.
I can’t seem to be able to reproduce on my end, I’ve asked some colleagues to give it a go too and they were able to sync their tasks suscesfully. I would recommend reaching out directly to our support team who has better tools to troubleshoot this type of issue.
Feel free to share the URL of this thread so you don’t have to re-explain everything you just said here.
So sorry for not being able to help further via this forum with this specific issue! I hope this gets resolved asap!
