Using:
InDesign 21.1
Link created in Illustrator 30.2.1

I have a map created in Illustrator with a background (flattened) tiff which displays fine in Illustrator. Once placed into InDD, the tiff won't appear (layer is ON and printing) and doesn't get included in exports (thus eliminating a rendering issue of any kind).
This has happened on 2 separate files but is fine in others with the same set-up.
On occasion the tiff will reappear...
This is a recent 'development' in past 2 weeks.
