Discovered Serviigo after downloading, trying, and then deleting about 30 Android apps on my Samsung GS7. Only Serviigo saw my Serviio server and played the files therein. Very happy.
I believe I saw that Serviigo requires the "Pro" version of Serviio in order to receive the media. Is that correct? My Serviio installation is less than 1 day old so the "Pro" trial period must be enabled for now.
Just in case anyone is interested, I have been running a TVMobili server (on an older Mac). The clients are Roku's (Stick, and Roku2). But the old Mac is starting to fail and I thought I'd give Serviio a shot on an old Dell Vostro laptop that is running Windows 10 (no problems!). The Roku's are perfectly happy with Serviio on the Vostro so it seems I'm ready for the switch. (I'm only using LAN access.)
While I don't seem to have any issues, advice from those more experienced in these matters is always appreciated.
