Bug: Device groups not loading on startup (Shows "Unknown" folder) - Resolves after reopening

Hi everyone,

I'm experiencing an annoying glitch with my TeamViewer desktop client regarding my device groups.

The Issue:
When I turn on my computer and TeamViewer launches on startup, it fails to load my actual device folders. Instead, under "All Groups," it only displays a single folder named "Unknown" with a refresh/sync icon.

The Workaround:
If I completely close the TeamViewer application and reopen it, the issue disappears. All of my folders and devices load perfectly fine right away.

My Details:

TeamViewer Version: 15.75.5

OS: Windows 11 Pro 25H2

It seems like the app is struggling to sync or draw folders properly during the initial boot sequence. Has anyone else experienced this, or is there a known fix to get the groups to load correctly on the first try?

Thanks in advance for the help!

Hi Nadin,

Reinstalling the app does not solve it
On web it shows fine, the issue is related to first app draw on login

Hello @IvanCarlos,

Thanks for reaching out and for sharing your observation about loading your device groups during startup.

I've forwarded your case to our development team, and they confirmed that this is a known issue and that they are already working on a fix.

To make sure you don’t miss the update once it’s released, please keep your TeamViewer on both sides of the connection up to date. You can always find information about the most recent versions in our Changelogs.

As an additional step, it’s still worth trying a clean reinstall of TeamViewer Remote. You can follow our step-by-step guide in our Knowledge Base article: Uninstall TeamViewer
After uninstalling, restart your PC and install the latest version again.

As a possible workaround, it might be worth checking whether this behavior occurs in the TeamViewer web client.
For more info about the web client, take a look at Blog post Advantages of Using the Web App

Thanks for your patience and understanding. Feel free to let us know how the reinstall and web client test go.

Best,
Nadin
