Since a recent Adobe Acrobat DC update, button styles set in InDesign are no longer working. They still work when the pdf is opened in a browser.

Steps to reproduce the issue: Create a radio button or checkbox in InDesign. Customise the style appearance for the on/off settings (colour, shape, text, removing default checks and dots, etc.). Export to Interactive pdf. Open in Acrobat. Button off styles have now reverted to default style settings. When you click on a button, it briefly shows the correct on style, but once you click off it reverts to the default style again.

Environment: InDesign CC 16.3. Adobe Acrobat DC 21.0. Windows 64-bit.

Expected result: button styles set in InDesign remain activated in Acrobat.

Observed result: styles revert to default settings in Acrobat.
