Is there any videos on how to send from nano wallet to depot wallet mosacic?
In nanowallet you must tick “mosaic transfer” check box. It should be easy. You must only watch if you are not sending by mistake xem as mosaic.
I don’t know deptowallet but it should be possible also import private key from nanowallet into it.
