Quick Update:
New SSD received and installed.
All is now working. Above issues are now resolved
However, one question. When Polisy connected to the ISY994i, in PG3 dashboard it shows all node servers from the ISY994i but in an unmanaged state. Some of these are no longer used and seem to be an old polyglot none server entries so I may have expected them in the PG2 (Depricated) dashboard but not PG3. I can't find a way to remove them so they're taking slots that I want to reclaim.
See attached.
Thoughts?
