Yes I’m experiencing the same and have escalated it to their technical support before, and every now and then they were able to resolve it. So far the client always notified me of issues with the sync process (the windows client that is, Android is very basic). I’ve also been begging for a Linux client for 5 or 6 years now, to no avail.

So yeah while I’m happy with it as a storage solution in general and like the responsiveness of their support, there are still a few issues here and there. I’m in the solo basic tier and don’t use more than 400GB of the storage, so that’s plenty for my use case.
