Bug?: tracking links work from pc but not from mobile?

due to security reason i would prefer not to add links.
What can i add is that today is working from the mobile too.
Probably was my fault with the mobile.
I will give you more informations about this problem if will happen again

Can you document this more thoroughly. Describe exactly and paste in the links. Tell us how you sent the mails (did you forward them or anything strange).

(I would think) The links should be fine in any situation, as it’s basic html. Therefore, there must be some other strange factor causing this issue.
