hmm…
is network manager installed/controlling your connection? this was the issue for someone i helped a long time ago with the same issue of static ip stuff:
can you check the service via systemctl status
should get long list and one of them is dhcpcd service.
├─dhcpcd.service
│ ├─383 wpa_supplicant -B -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -Dnl80211,wext
│ └─468 /sbin/dhcpcd -q -w
└─cups-browsed.service
└─23277 /usr/sbin/cups-browsed
pi@screenlypi:~ $ systemctl status | grep dhcp
│ ├─ 3742 grep --color=auto dhcp
├─dhcpcd.service
│ └─468 /sbin/dhcpcd -q -w
pi@screenlypi:~ $
