What would security/privacy experts recommend in this situation? It sounds glib, but the obvious and best recommendation is to delete both Facebook and Instagram apps from all of your devices. It's not feasible to expect to use apps such as this – whose primary design principle is to track and extract as much data as possible from it's users – without being tracked cross-app and cross-device. For a similar reason, when I launched my adblocking app (https://www.magiclasso.co/ https://www.magiclasso.co/) I didn't release an Android version. It is a losing battle trying to work against the key reason that something exists. In the case of Android it is owned and developed by the world's largest advertising company, so it would be futile trying to create a privacy and security first adblocker in such a hostile platform and environment.
