Assuming your LDS Account has your membership number recorded correctly (if you can see your ward directory and/or calendar on lds.org then it probably is), then we generally recommend waiting 24 hours to make sure the permissions have propagated completely. Usually it's faster than that but if something is down it sometimes takes a bit longer.
If it's been that long then make sure your LDS Account actually has your membership number (and not say your wife's) by going to
https://ldsaccount.lds.org and clicking on the Membership tab. If that is correct and you still don't have access then have another member of the bishopric go into LCR and make sure your calling is recorded using the standard calling and not a custom calling (a custom calling will have a star by the calling).
