I agree with the others that have objected to this, as this has entirely broken Ubuntu 18.04 at our company, too. We have a NAS which hosts all user HOME directories, from wherever they may log in.
Unfortunately, this snap stuff fails miserably in such an environment, and there should be a way for you to accomplish your goal without breaking something that we've been using on various *nixes for 30+ years (e.g. Solaris, AIX, HP-UX, SUSE, RHEL, and even Ubuntu up to recently). We are still running Ubuntu 12.04 in some places as your NFS support has gradually degraded over the years, and we're seriously contemplating moving to CentOS/RHEL which seems to be much more enterprise-friendly.
