Users have observed a severe bottleneck in ConnectALL performance in Jira with the Jira adapter.
Atlassian informed us that this is due to ConnectALL using a normal user account rather than the preferred appuser to update Jira Cloud. The appuser has a higher threshold which would increase throughput.
It will be necessary to use the Jira Oauth2 option. Use the Jira link below to set up Oauth2 on the Jira application. See Notes below the link for configuration information specific to ConnectALL:

NOTES specific to ConnectALL when enabling Oauth2 (to be used in addition to the Jira link above):
