Hello,  
  
  
  
We’re using a hosted Mautic and have been implementing A/B testing to most emails just fine. We’re currently using v2.1. And from the prior update to the current release split testing just stopped working.  
  
  
  
What to check? Any help is greatly appreciated.  
  
  
  
Thanks!

Hi. Are you using 2.1.0 or 2.1.1?

Thanks,

Hi,

We’re using 2.1.1 and has already applied the fix here: [https://github.com/mautic/mautic/issues/1520](https://github.com/mautic/mautic/issues/1520). Ran a test a while ago. Still not working.

Would appreciate any help.

Thanks,

Vik

Anyone can give a hint on where/what to look?

Thanks.
