Connection to the app while recording

Hi. I’m recording a photo intervallic time lapse for a mural being painted over a 5 day period, using the Insta360 X2. Settings are 2min intervals. I began recording thru the app, but occasionally I lose the connection with the camera and the phone. Will it keep shooting during those gaps? Also, recording will only take place during office hours. Can I remotely begin and end recording thru the app, or do I have to physically be there to turn it on and off?
