If you submitted an approved official weigh-in within 48 hours, you may be able to use that weigh-in for other games. When you go to submit your weigh-in for the new game, a prompt will appear asking if you’d like to reuse your previous weigh-in. Just select yes, then submit, and you’re all set! If you’d rather submit a new weigh-in, just decline the option and submit your weight as usual.
If you are not prompted to reuse the weigh-in you will need to take and submit new photos. Also, If you have had a weigh-in rejected in the meantime, the option to reuse will not be available.
