Hi, community members! I have a strange issue working with images stored in AF.

I store them as byte array in AF attribute and send some updates to the attribute. This part works fine so no errors here.

The tricky thing appears in PI Vision, I display this image from attribute using custom symbol, displaying works fine too, but data update doesn't.

What I mean is that after I update the attribute,  new value appears  in AF in few seconds, but this value becomes accesible in my Pi Vision symbol only after few minutes that is very long. What can cause such a long lag between data update in AF and sending this data to PI Vision symbol? Other attributes updated quickly in PI Vision.
