App used to be great for Fi users, but latest updates have rendered it useless. Now the app refuses to acknowledge Wi-Fi is connected, crashes when trying to save settings, and complains that it can't log on when first starting, even though it shouldn't be trying to log on to anyting. Can't seem to uninstall the updates, so I guess it's time to find a new app.

Used to be great before this past couple updates. I used it often to repair or change providers (Google Fi) when I didn't have data or Internet connection with the current provider. Now, you must have Internet connection to even open the app to get the repair codes. On top of that, the app now requires invasive permissions that it did not need before the update. So this app is no longer useful to me.

We are sorry to hear you do not like the new updates. It sounds like the things that are bothering you are things that we can definitely make some updates and enhancements too. Can you send an email or support ticket in and let us know what the permissions that are invasive are. To my knowledge, we haven't added any new ones but we will take a look

This app has been great over the years as a Fi user, and I've found it a little easier to use than some of the others I've tried. I'd love to see a few more details about the connection strength in the app, tho, and it would be nice if it showed info about the Pixel series' Dual Connect capability. Also, unfortunately, I'm not sure how much longer it's useful without 5G support or now that Sprint has been fully merged into T-Mobile and I'm not switching between networks any more...
