I am working on a ArcGIS Pro Addin. The ribbon was good in ArcGIS Pro 3.2. After upgrading to 3.4, some of the buttons don't load properly anymore. All of the buttons are 32px by 32px png. What could be the issue?
// Some sample code
<group id="CommunityVizPro_ComponentsGroup" caption="CViz Pro Analysis Components" appearsOnAddInTab="false" condition="cvpro_isCVAnalysisCondition">
<button refID="CommunityVizProModule_ShowScenarioManagerButton" size="large" />
