I have an updated session <kuid2:608277:100371:12> for Roy's TRS19 Canadian Rocky Mountains Baker Crk to West of Calgary route <kuid2:122860:101519:71> which is on the Content Store (simc:524). I've tried to submit this update via the TCCP route, but this fails because permission from the route's owner (roystrainz) is missing. Sadly, this permission can no longer be obtained as Roy passed away at the end of December 2023. What do I do now?
