All is in the subject line,
as we are still under that major disturbance,
and I can see unusual frequency moves on remote KiwiSDR here in Europe.
edit : some GPS referenced oscillators may be fooled by the bad ionospheric conditions,
OR they may also give up and revert to an internal quartz in place of the missing GPS signals.

Quite possible. NOAA SWPC reports a 24-hour peak in the R3 radio blackout range, though there were some instances of near R4 levels. ~R4 can affect GPS systems.

It would not be surprising if isolated areas on the sunlit side of Earth might have reached even R4 given the considerable power of the recent CMEs.
There is a 75% forecast chance of R3-R5 levels through May 13 UTC.
Farmers in online communities all over the internet have been discussing the GPS outages, with some saying that they’ve been running into “very weird issues.”
