Cannot read some tags inside Rockwell AOI

Wow. Is this really the case? We’ve used custom and builtin AOI’s quite heavily on many systems. It makes development on both the PLC and HMI side much faster. Has this always been the case or is it something more recent? I haven’t really noticed any issues with older 7.9 systems, but 8.0 possibly is slower to read stuff?

We have several templates going to AOI’s and I had them working pretty well on 8.0.14, but was suggested by tech support to update to 8.0.16 and now they run super slow. Think it is mostly because of the tag() function within expressions tho? This seems to be a bug in 8.0.16 Vision. How much of that could be due to AOI’s?
