Ring 3 doorbell audio and motion alert issue

hi, i recently got a Ring 3 video doorbell, seems working fine after installing a Chime Pro to extend wifi outside the door,i have motion freq. to Frequent, 15/30 feet, i noticed now that watching recordings videos,some of them the audio starts only after 15 seconds.Another thing is the motion is not detected or i don't have notifications right away, i set up first to 5/15 feet and the lower part off otherwise i have alerts for cars passing by in the parking lot, i am on 4th floor in a condo apartment, so i need camera on left/right and for the first 8 feet in front of the door. i just tried to switch the connection of the Chime pro to 2.4ghz instead of the 5ghz..let's see...( question: i changed only the wifi frequency to 2.4ghz at ChimePro, do i need to change anything to the door bell settings? i understand that the doorbell is using chime pro frequency so i guess i don't need to change anything to it but i want to confirm it please)
