We tested and everything is normal.
Please answer the following questions as many as possible,
so we can provide better support for you.
1. ReaSnow S1 firmware version/ APP version
2. your console and game
3. settings in the game on console, such as sensitivity, dead zone, acceleration, aim assist, etc.
it's better to restore all settings in game and change the settings as shown in our APP, and try it again with a default game config.
4. which config has been activated in ReaSnow S1?
your settings for HIP/ADS /HIP YX Ratio/HIP MIN/ADS YX Ratio/ADS MIN/curve in this config
5. a video to show us your trouble
please upload the video to youtube or other file-sharing servers, and send us the URL.
