Symbols are displayed as stretched or compressed (incorrect width) after being imported into ArcGIS Enterprise from an export package.

Workaround

• Use 4.x Map Viewer and ArcGIS Experience Builder which supports ArcGIS Pro symbols and therefore, the 'Use symbols types compatible with all clients' check box can be disabled at the time of publishing.
• Uncheck the 'Use symbols types compatible with all clients' check box and accept that symbols are downgraded in Portal for ArcGIS Map Viewer Classic.
• Avoid symbols with a big height or width difference and favor symbols with the general shape of a square to avoid distortion.
