iPhone with Google Fi

Like many families these days, we are feeling the pressure from the cost of everything going up. One of the expenses we can make changes to and ease things a little is our wireless plan. I have several options I can consider but have been looking at Google Fi. We have iPhones and do tend to be on WiFi most of the time so the Flexible plan is appealing.

I am mostly looking for impressions of how well iPhone and Google Fi work together. I know Google Fi’s support of the iPhone has improved over time but are there any notable limitations?
