Odd problem that only cleaning the cache solves it

I need some direction trying to find out what is happening in my production environment, maybe someone had a similar issue and can help. Every now and then my list of documents (from a firestore db) vanishes, usually after a document is edited, and the only way to make both the app and the browser version to resume working is to clean the cache. That being said, the actual problem is the lack of consistency in this, it happens from time to time, there is no step-by-step way to reproduce it nor have it ever happened in the dev environment. Any ideas?
