@ron k103 Following up with an update! While our development team continues to investigate they have recommended trying to migrate to our new Jira integration experience which they believe may resolve this issue for you. Your account admin has received instructions on how to do this via email but for your convenience I'll link the steps for them to take here as well.
For context this new integration enhancement changes how Lucid connects with Jira data on a board allowing Jira data to sync much faster. This reduces the amount of time required to import create convert or sync Lucid Cards at scale and improves product performance.
