I've been using a de-googled phone for about a year now (CalyxOS, uses MicroG) and I have yet to run into an app that behaves differently than when I used the stock OS for my Pixel. I've even tried downloading Google's apps and they work the same, no hiccups (Maps, Camera and Translate for me). CalyxOS includes a firewall that can disable network connectivity on a per-app basis, so one could even just use downloaded maps/translation sets with Google apps if they wanted. Again, this is just my personal experience--I'm sure there are apps out there that deliberately throw a fit when they detect a custom-signed OS running on your phone. I just have yet to see that in any of the banking, social media or productivity apps I've used.
