Spaces getting too big results in failed WorldAnchorTransferBatch.ExportSync

So apparently one of my "Spaces" was getting big, namely 300 MB. Not sure how this works internally but it seems to accumulate over time.

I was trying to send a world anchor to other Hololenses and the WorldAnchorTransferBatch.ExportSync failed with "Unknown Error". First off, that error message is not very helpful at all and should be fixed in the SDK. Secondly, clearing the space (Settings->Spaces) made everything work again. Blazing fast I might add.

However, it is a mild inconvenience that the users need to go into the system settings every now and then to clear this.

Does anyone know if we programmatically can clear spaces?

    This is not quite what was happening to me though. I think the Hololens should in fact have an overlay where the user is asked if Spaces can be cleared. My error doesn't even give a hint on WHAT the issue is. i.e. "Unknown Error". At the least the SDK should provide information on why it failed.

    Thanks for the information though.
