That doesn't make sense, if your PON led is flashing green rather than solid red, you have physical connectivity but no activated service.
After a call to BT it turns out I don't have to fill out a notice of interest form, but Openreach are going to have to complete more work at my block of flats to get full fibre working.
So the saga continues.... 😬🥸🤠🤖💀👻
