Ok so as the tips in the link are now working.
And I assume the diagnostic test on your Samsung Members App does not highlight any issues.
Can you try Put the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops. https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/ just to see if any app is affecting this.
Please also double check any relevant preferences settings.
One final self help troubleshooting tip is to back up and factory reset.
Also a Samsung Experience Store or Samsung Service Centre can take a look but they would ask if you've tried a factory reset first @Eyes14

The advice I offer is my own and does not represent Samsung’s position.
