Same issue here. Which update version broke it for you?

The August 2023 Samsung OS update was a problem for me. Cleared cache and reinstalled — took two tries.

Try going to Settings > Apps > [AppName] > Clear Cache first. Then try Clear Data if cache doesn't fix it.

Clearing cache alone didn't help me. Had to do a full reinstall.

The reinstall worked but my login wasn't saved. Had to re-enter everything.

I had to downgrade the Samsung firmware to get mine back working. Bit extreme but it worked.

 

[LauraApps]

How do you downgrade Samsung firmware? Didn't know that was possible.

 

[TomBuffer]

Samsung has a USB firmware downgrade process. It's on their developer forums. I can link the process.

After the last Samsung update I noticed the app uses more memory. Check your TV's available RAM.

My fix was turning off HDMI-CEC which apparently was interfering with the app somehow.

That's a weird fix but I'll try anything. Mine has been broken for three weeks.

Solved mine by factory resetting just the Smart Hub, not the whole TV. Takes 2 minutes.

Smart Hub reset! That's the one I hadn't tried. Working now! Thank you!

[SOLVED] Smart Hub reset fixed the issue for multiple people here. Mark your TVs accordingly.
