I have noticed that obstacle avoidance works well, but when i switch modes and then back to P it doesn't  work. Yes i am in P when i test again.

I have to go into the app and disable and reenable the settings for it to work again.

Is anyone else seeing this behaviour?

I Have tested my phantom 4 this morning. the obstacle avoidance was working as expected when switched from P to S or A then switched back to P.
Have you done the front sensors calibration from Assistant 2 software?

Hello, was there a red line on the sensing icon when you switched the mode back to p mode? It would be better if you can provide me the firmware version and app version here.

Could you please provide your flight data, so we can analyze the issue. Thank you!
