I couldn't enter my picture in this challenge with the correct exposure date. 10th September 2017
So I left a comment in the description and entered it within the allowed dates ( between Sep. 20th 2019 and Oct. 3rd 2019)
That's fine -- there's a known glitch which causes the system to reject certain dates, even those taken within the allowed dates if "too near" either the beginning or end of the submission period.
