Welcome to the Q&A Forum

Hi Allison, any updates on this? From my understanding, it is possible that Google is not indexing the mobile versions of pages if they are simply corresponding to the desktop pages (and indicated as such with the rel=alternate mobile switchboard tags). If they have that information they may simply index the desktop pages and then display the mobile URL in search results. It is also possible that the GSC data is not accurate - if you do a 'site:' search for your mobile pages (I would try something like 'site:domain/m/' and see what shows up), does it show a higher number of mobile pages than what you're seeing in GSC? Can you check data for your mobile rankings and see what URLs are being shown for mobile searchers? If your data is showing that mobile users are landing on these pages from search, this would indicate that they are being shown in search results, even if they're not showing up as "indexed" in GSC.
