I submitted a paper to an international conference, but the registration fees were initially undetermined. Once the list of accepted papers was published, the conference website provided information about the registration fees with some reductions offered for participants from low-income countries. However, two weeks later, the registration details were unexpectedly changed, and no reduction is now available. This situation has left me unable to participate, even though I had already committed to preparing and submitting my camera-ready paper based on the previous registration information.
Given these circumstances, I am contemplating whether it would be appropriate to communicate with the conference editors to request a reinstatement of the reduction option.
