Only account owners can access the Account page in the app.
Changing your plan
You can Downgrade or Upgrade your GoDataFeed subscriptions at any time from the Account > Subscriptions page by using the Change Plan button in the subscription details.
Changing your plan is effective immediately. For example, if you upgrade your plan to Ultimate, then you can access import filters right away. You will be prorated for the change in the subscription.
If you are in your 14-day trial period, you can change your subscription and the activation date will stay the same. You will only be charged for the subscription level and usage amounts on the billing date after your trial.
