Ahh bummer. Thanks for the info. I am using their assisted custody service right now, but wanted to do some multisig testing with a family member that lives in another state. I supposed I can do it with sparrow and am comfortable handling the PBSTs, but unsure how to get started with creating the wallet descriptor with a remote signer.

You can do this with Keeper - though only one wallet will have insight into balances and send/receive functions. The other phones still just serve as signing devices.
Here's a video that will start at the part with multi phone collab!
Thanks! I will try some stuff out today!
