XF 2.3 Trust this device never works on cell phone

[gambler]

I can't seem to shut off this 2-step verification request on my cell phone when the 30 day box has already been checked repeatedly.

No issues on my PC as the 30 trust rule seems to work, but my phone, which uses my own wifi, will ask for this code every time I login to my forum. The IP should be the same each time.

Is there a way to set this off without turning off the 2-step verification completely?

Thanks!
