Hi,
We are develope commands for arcgis pro sdk 2.2 version.We have developed the "Intermediate distance writing " tool.Tool lines are feature class, distance string is the annotation .But annotation (distance string) when I create new one store annotation correctly in table but not shown stable in map. When create a new sometimes when I use zoom in/out (change scale), some annotations or all annotations don not display.When I create a new one sometimes all the annotations appear. Here is the Pictures and Codes below. How can I solve this problem ? Could this problem be a bug?
