Salesforce Zoom for Lightning App bug

[brfi]

I installed SF Zoom for Lightning (ver 2.27). When viewing "Permitted Users" column in "Manage Connected Apps", it always displays "All users may self-authorize", even though when I go into "Zoom Integrations Oauth" it shows what I changed it to, "Admin approved users are pre-authorized". I don't know if this is what was causing the issues that I experience (incoming calls did not pop up the Salesforce Lead even though the softphone layout setting "Screen pops open within" is set to "Existing browser window". When I changed "Zoom Integrations Oauth" "Permitted Users" setting to All users may self-authorize" that issue went away. However, when it comes to outbound calls, the Salesforce Lead still does not pop up.

To recap:
1) "Permitted Users" was set to "Admin approved users are pre-authorized", but in the Manage Connected Apps screen, it always shows "All users may self-authorize". I suspect that it is neither one or the other, but somewhere in between.

2) On outbound calls, the Salesforce Lead does not pop up.
