The response on enabling instant personalization is for (;;);{"__ar":1,"payload":true}
abd the post is :
Parametersapplication/x-www-form-urlencoded
__user 100001898439919
el instant_personalization_checkbox
fb_dtsg AQBHlCZB
opt_in 1
phstamp 16581667210867906684
Source
el=instant_personalization_checkbox&opt_in=1&fb_dtsg=AQBHlCZB&__user=100001898439919&phstamp=16581667210867906684
where using source is not feasible since FB phstamp keeps changing so I can't use source while using source we can update the instant personalization value.
Please let me know if there is any other way to do this without using phstamp
