Since our organisation decided to consolidate all survey activity on to Survey123 we have seen an increase in pressure on our named user accounts in AGOL - we are running out!
As many of the new survey only users only carry out surveys infrequently we thought that we could just disable their accounts until they need them again. Unfortunately it is documented (Manage members—ArcGIS Online Help | ArcGIS) that disabled accounts count towards the organisation's total. This seems strange as it means we're paying for something that can't be used. It would make more sense for disabled accounts to not count towards the organisation total.
