Converted ArcGIS Pro Annotation (geodb_pro_annotation) to Standard Annotation (geodb_annotation) with the help of Dynamic File Geodatabase reader and Dynamic File Geodatabase writer. Enclosed the developed FME workspace template for your reference.
However, when opened the generated output Standard Annotation (geodb_annotation) feature class in ArcMap (version 10.8.1), getting an error saying "One or more layers failed to draw".
Please refer to enclosed screenshot from ArcMap and help to advice how to handle this situation.
Found no issues with the output when used Static File Geodatabase reader. However in our case, need to use the Dynamic File Geodatabase reader only.
Thank you..!
Note: Enclosed FME workspace created using FME(R) 2022.1.0.0 (20220704 - Build 22618 - WIN64)
