I'm still new in Power Apps,
I'm facing the issue when two drop-down list displays by using Office 365 Group connector.
when 1st drop-down list change, then second drop-down list change accordingly.
The 1st drop-down list Formula is Office365Groups.ListOwnedGroupsV3().value.displayName
The 2nd drop-down list Formula is Office365Groups.ListOwnedGroups().value.id
The data should be:
Group Name - Group ID
Herewith my screenshot.
I'm solving by using the following formula.
Filter(Office365Groups.ListOwnedGroupsV3().value.id, id = ddlgrouptest.Selected.id)
ddlgrouptest is my first dropdownlist name.
