Using the latest InDesign 2022 (17.2.1) for Mac (The Middle Eastern version--the one that shows English and Hebrew), both on an M1 Mac mini and a late 2015 iMac running Big Sur.

Import a docx Microsoft Word file into an InDesign file (tried with blank new document as well as one of our templates) with the import settings set to bring in all styles.

The file is imported but the import has stripped all styles from the document.

Resave the docx file as a doc file.

Import new file into ID, which results in all styles being visible as is expected.
It is my understanding that a restart may also help, but is required each time.

I can submit a file as needed.
