Hi there,
I am currently using the trial version of this app. It works fine on the original Team site that I added and activated the app to. However, if I add it to any other site within the same site collection/domain and try to activate the ribbon I get the error message 'Unable to update ribbon buttons.'
When I go to the Team site, within the ribbon the app button is there but disabled even after I managed to get the ribbon added on one of the site. Is this happening as I am still using the trial version?
Thanks in advance!
