Hello Mohammed,

Is there any work around in the mean time?  Report was working fine, then suddenly, it stopped working.

Hello Yongke,

The bug is fixed in the latest internal build. Give it a try and let us know how it goes.

All the best,

Hi Peter, the internal build does indeed work.  Does it matter if I buy the product or use the demo?  Will I be still able to use this build?

----------------------------

Also, I have noticed another bug introduced in this internal build, please check screenshots:
