iPhone native client: preheader issue since iOS 11.3 update
Hi guys,
a colleague reported issues w. the preheader not being displayed properly anymore on his iPhone since he updated to iOS 11.3.
Instead of text, part of the open tracking pixel URL (which we are placing at the beginning of our emails) is shown as preheader.
Does anyone else have similar issues?
Any help would be really appreciated :-)
Thanks, Ingo
