If you’re looking for the ITVX Help area, it’s over here.
We are aware of an issue with Samsung Galaxy Tab A7 devices which is causing videos to lag.
Unfortunately, this is not an issue with the ITV Hub app and the issue appears to be affecting other video on demand apps.
Samsung have provided troubleshooting steps which may resolve the issue. These can be found here: https://r2.community.samsung.com/t5/Tablets/samsung-galaxy-tab-a7-2020-lagging-while-video-playback/td-p/5790905
If the issue persists after completing those steps, we kindly ask that you contact Samsung directly as unfortunately there is nothing we can do to resolve this.
