Newly added devices missing in Alexa App

Hi,Earlier this week, I added the Ring alarm and a few sensors. They showed up in the Alexa app without any issue.Yesterday, I added more sensors to the alarm system and a Doorbell Pro. None of these are discoverable, or appear in the Alexa App yet.All sensors and the doorbell are recognized and work fine in the Ring appThe Alexa app's "Discover Devices" function doesn't find the new devices, but has no issue connecting to the first batch.I renamed a couple of sensors. The first set show up with their original names on the Alexa side, the new ones don't show up at all.I disabled the Ring skill and re-enabled it.So... the delay for new devices to appear is much longer this weekend than earlier this week, or there's a problem in sync'ing the Ring devices (new names for earlier devices, and newly added devices). If there is a necessary data exchage between Ring and Alexa back-end systems, is there a way to trigger an update?
