Back at my previous job, the moment I realized things had changed was when nobody seemed to know who owned certain features anymore. We were still acting like a tiny startup even though the project had grown a lot. I ended up reading a few articles, including https://geomotiv.com/services/dedicated-development-team-services/, because I was curious how other companies deal with scaling teams. It made me think that growth often creates communication gaps long before anyone officially admits the structure no longer fits.
