For me it only doesn't work with Spotify

[SalarMohammadUzair]

Facing the same issue, even though the YASB media player detects it.
For me, the widget appears for a split second and then vanishes

[nixy595]

just close and re open it that's what works for me

even restarting PC doesn't work, there has to be a bug with the program

[unchihugo]

Hi guys, is anyone able to upload logs? Without them it's hard for me to figure out what's going wrong.

[SabaJepeto69]

The logs just don’t exist for me

[unchihugo]

The logs just don’t exist for me

There's two places they could reside in:

%appData%/FluentFlyout
or
C:\Users\USERNAME\AppData\Local\Packages\unchihugo.FluentFlyout_69b7b6qge1ahj\LocalCache\Roaming\FluentFlyout

Could you check if they're in either directory?

They do exist for me in the second directory, shall I paste the raw text over here?

Hey, I'm having the same problem here.

Contents of log file right after I open the app are the following:

If I hover my mouse on the spot where it should be on the Taskbar, it shows the current song details, if that helps

[unchihugo]

Thanks guys, this helps out a lot - I'll start looking into this.

EDIT: did the taskbar widget always not work for you guys or was it due to a recent update?

It worked fine yesterday. Today it's gone lol. I don't think windows has updated (I guess it could have done some minor update in the background, idk) neither did I update the app.

[xlysander12]

Some new information for you @unchihugo :

When I changed the screen's resolution it appeared again and now it's showing properly

[unchihugo]

@xlysander12 that helps out, thanks!

I can't reproduce the issue, so if you're able to (or anyone else here), could you back up your current settings, then downgrade to v2.7.2 and see if the taskbar widgets work fine then? It would give me valuable information!

[SabaJepeto69]

@unchihugo ive downgraded to v2.7.2 and its the same for me.
