I've just noticed the same problem. https://kb.daisy.org/publishing/docs/metadata/schema.org/accessibilitySummary.html states that "If the summary does not offer any new information, the property can be omitted from digital publications."
A relevant statement is here: "accessibilitySummary metadata is now recommended (SHOULD), not required (MUST). The impact/severity is downgraded from serious to moderate."
Please provide the following details if possible or relevant:
Ace currently flags EPUB publications for missing the 'schema:accessibilitySummary' metadata, while the EPUB Accessibility 1.1 standard indicates that this metadata is no longer mandatory (unlike EPUB Accessibility 1.0).
