Ah interesting. Alright. Thank you,
I don't believe any additional lines are added in these emails .. I haven't noticed anything. I will have to take a closer look.
And, yeah, my question would be if it's line break / row related, then why the heck does approve / reject work..
An update for you - a defect is being raised as Nintex were finally able to replicate our issue (so we weren't just going mad!).
A workaround for now which works for us is to reply with the phrase and delete the rest of the email body!
Ahhhhh! Thank you, good to know!
