Also, I do as @jkingslake does above and set the `cache_timeout=0`. From [GCSFs docs](https://gcsfs.readthedocs.io/en/latest/api.html#gcsfs.core.GCSFileSystem) `Set cache_timeout <= 0 for no caching,` seems like the functionality we desire, yet I continue to only see the un-appended zarr ","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1030811490

However, if you read the file immediately after appending (within the 3600s `max-age`), you will get the cached copy. The cached copy will still be of shape `[3]`--it won't know about the append.

Ignorant question: is this cache relevant to client (Jupyter) side or server (GCS) side?  It has been well over 3600s and I'm still not seeing the _appended_ zarr when reading it in using Xarray.

> To test this hypothesis, you would need to [disable caching](https://cloud.google.com/storage/docs/metadata) on the bucket. Do you have privileges to do that?

I tried to do this last night but did not have permission myself.  Perhaps @jkingslake does?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1030811490

I had no idea - makes sense in general but slows down testing if no known about!  Anyway for my case, when appending the second Zarr store to the first, the Zarr's size (using `gsutil du`) does indeed double.  I'm new to cloud storage, but my hunch is that this suggests it was appended?

> Can you post the full stack trace of the error you get when you try to append?

In my instance, there is no error, only this returned: `<xarray.backends.zarr.ZarrStore at 0x7f662d31f3a0>`
