Lags with ATC and traffic display

Good morning/evening.

I use Navigraph Charts on my tablet. It’s a Samsung Galaxy Tab S9 FE. The app lags a lot on my device when traffic and ATC is displayed. When only ATC is displayed there is no lag. I think the traffic display should be optimized. I don’t know if the problem is with my tablet’s performance. Nevertheless, it’s a great idea and a very useful feature. Thanks for this.
