Which issues are you referring to?
Generally speaking bugfixes/workarounds/feature changes and unresolved problems are all reported on relevant Release Notes...so a quick check of latest HPE OfficeConnect OC20 page (select OC20 Access Point from the dropdown menu [*]) should give you an idea of the product status from the point of view of its known issues (solved/unresolved, if any).
Check about it here.
From the point of view of Security, if you have security concerns about it then check the Hewlett Packard Enterprise Product Security Vulnerability Alerts page (it's for EMEA, shouldn't be too difficult to find the US version, if any).
Security Bullettins archive can be found here.
[*] For Release Notes of:
- HPE OC20 802.11ac (US) Access Point (JZ073A)
- HPE OC20 802.11ac (RW) Access Point (JZ074A)
have a check here, as input use the SKUs provided above (JZ073A and JZ074A)...if you find yourself in a loop (not finding what you're expecting to find into the HPE OfficeConnect products page) skip this search and go directly here (from HPE OC20 FAQs page available here).
