I've had this happen for the same user twice now. She works remotely, and I'm wondering if that's the commonality, but I have other remote users who it doesn't happen to. What happens is she opens our FileMaker app, the interface loads but no field data loads. The solution is for me to go into her Users > username > Library > Caches > FileMaker folder and delete the contents of ContainerCache, DBCache, DBFileThumbnails. Then the database loads again. It's a weird issue and it feels like a cache corruption. Would be nice to have a button in FileMaker preferences to clear the cache.
