I've just thought of a couple of things to take into consideration when turning some of your apps into PWAs.

Firstly, if you use a firewall/VPN combination - as each PWA will be considered as requiring the same ruled as your browser. This could accidentally allow your location to be known under certain circumstances.

Secondly, if you're on mobile and have energy-saving when you go low battery; you might encounter weird behaviour, such as log outs or restarts, when your energy-saving kick in.
