@javax6: you write ".. using the GUI in settings > wifi > select the SSID used > edit > IPv4 > from Automatic to Manual" which presumably means you used Network Manager to configure the network.
If that is the case, then /etc/network/interfaces is not used. There are many (incompatible) systems and frameworks for configuring networking, so you have to decide which one(s) to use.
For such a static configuration I'd always prefer systemd-networkd (in combination with wpa_supplicant is WLAN).
I routinely "apt --purge --autoremove remove ifupdown isc-dhcp-*" (which are part of the default installation), and never install Network Manager or any such programs.
(if I had a laptop, I'd use wpagui).
