Also "Party Mode". Is that a problem?
I don't know. I was suggesting or asking about things that you may have set up differently to me...
...and here is one;
On the PC under "File > Quick Play > Playlists > Recent Playing Now's" I can also see and load my last playlist on the PC.
It actually took me a while to work out what you meant by that. I almost never use the File menu at the top of MC, and never use Quickplay.
Do you have the Navigation Bar visible on the left of MC?
Do you see the items "Playlists > Recent Playing Now's" in the navigation bar?
Do you see your recent Playing Now's in that item?
If your recent Playing Now's appear in "File > Quick Play > Playlists > Recent Playing Now's" menu, then they should appear in the Navigation Bar at "Playlists > Recent Playing Now's".
If your recent Playing Now's appear in the Navigation Bar at "Playlists > Recent Playing Now's", then they should appear in Gizmo.
The above has just always worked for me, and it works quickly. So we have to find what is different in your setup/environment/hardware. Or perhaps more correctly, what changed to stop Gizmo working in the last couple of weeks?
Do note that the "Recent Playing Now's" are automatically removed over time by MC. So I guess if there was a date issue on the PC or phone then they may never get added to Gizmo, or get removed immediately. But it is pretty hard to have the wrong Date and Time on a PC or phone these days, so that is unlikely.
While Gizmo connects to the server without errors, does that mean that you can select tracks on the PC using Gizmo, and play them locally to the "Here" zone without any problem?If so, the only thing I can suggest is that you clear Gizmo's Cache and Data from your phone, reconnect to the server, and then see if the "Recent Playing Nows" method starts working again. Here is how to clear the Cache and Data;
Here is a link that describes how to do that: https://www.androidcentral.com/how-and-when-clear-app-cache-or-data-android
I'm using a Sony XZ Premium running Android 9 Pie and noticed a couple of differences. So this was my process:
Settings
Storage
Tap "Internal shared storage"
Tap "Movie & TV apps"
Tap "Gizmo"
Tap "Clear cache"
Tap "Clear data"
Exit Android settings
Start Gizmo
Enter Access Key
At this point I am asked for the Username and Password for the MC Server I am connecting to. Note that these are the MC Media Network Authentication Username and Password, set under "Options > Media Network > Authentication", if you have it turned on, which you should. They aren't the PC Username and Password.
Once that is done, I am connected.================================================================
Perhaps they'll fix this in the future. In the meantime, $10 will get you an app that does what you want.
I don't think there is anything to fix, and I don't think there is any app that will do what he wants.
What he has described is that he wants to add tracks to Playing Now on the PC, which means adding them to the "Player" Zone, and then he wants to play those tracks using Gizmo on the "Here" zone.
When Gizmo is set to play to the "Here" zone it doesn't have access to the tracks in the PC's "Player" zone. Gizmo does have access to the PC's Player zone, and can see and control what is being played in the Player zone on the PC in Gizmo, when it is set to the Player zone.
Now if the Gizmo "Here" zone was visible on the PC, then Venom could select the Gizmo "Here" zone on the PC, add tracks, and then play them locally on his phone using the "Here" zone. But the Gizmo zone isn't visible on the PC, so that isn't possible.
