Hi, I can’t compare the 2 last version of this extension via your comparing tools:
"Response from JoomlArt Updater Service: Your account does not have enough permission to take this action. Please contact "JoomlArt Updater Service" for more information or use another account"
Are you referring to the compare tool in JA Extension Manager component? If so, please make sure that you set JoomlArt Updates as default services first and your account username and password in the authentication info
