Automatic approach in InDesign
You can avoid these problems by installing an update. In version 13.1 (CC 2018) the problems were solved. Excerpt from the official release notes:
Key issues resolved
- Tag for anchored text frame is missing.
- Anchored images are not exported when exported using the Articles panel.
- Next anchored figure gets tagged instead of the actual anchored figure with effects applied.
Manual approach in InDesign
If it’s not possible to switch to another InDesign version, the only manual solution is not to anchor objects. Whether this is realistic and reasonable must be decided on a case-by-case basis.
