Dynamic attributes: read value for attribute XXX has not been updated

Created by: stanislaw55

Hello PyTango community I am using dynamic attributes in my DS and everything works fine when launching DS instance. However, when I try to read one of my dynamic attributes, following error appears.

Read value for attribute XXX has not been updated

I've used examples from documentation to create DS. Have someone the same issue? PyTango: 9.2.2 Tango: 9.2.5
