sitting in homeoffice i just updatet to ios 13.4.
We use VPN to connect to the office - works well after the update (checked using filebrowser).
But the SIP registration in gs wave fails right after the Update to ios 13.4.
oh sorry - just made an additional restart and i`m back again
the initial restart after the update left gs wave without registration
So if you got problems like I - just make an additional restart
