Hey @Timberwolf,
You’re very welcome — we’d love to help sort this out.
The second issue you mention (blank screen and / or 0 album count) is a known issue that we have a ticket in for. I believe the two of us discussed about it here. We are sorry about the trouble 
As far as connectivity issues between your Core and remotes, I wonder if you could temporarily use a wired remote (for example, a computer) and see if you still experience these interruptions?
