+1, also experiencing this. Pixel 9 Pro, Google Fi, Release 2025032500. I started experiencing this after Release 2025030900.
I tried the suggested solution above from phillip to install Google Fi in other non-owner user accounts, and that seems to have fixed the issue for now. This seems like an odd fix, and it definitely had different behavior prior to this. I see that there is an issue on Github tracking the same problem: https://github.com/GrapheneOS/os-issue-tracker/issues/5059
