Hi experts,
After a recent major update, our client switched CRM to 9.0.2.751 from 9.0.2.449. Then their CRM does not enable the plugin we develop despite they uploaded updated assemblies. This plugin is crucial for their business. Actually, our own testing CRM hasn't updated yet so we cannot investigate if it's client side or plugin issue. The plugin works perfectly with previous versions of CRM.
Could you unshadow what may cause this issue?
