Modify resources
The resources available to your account (items, users, storage) are determined by your subscription plan. To adjust them, log into the web app, select Settings in the main menu, then click Subscription — this opens the account's subscription page.
Click Change plan, select the plan that matches the resources you need — on plans that support it you can also adjust the number of user seats — and confirm the change.
In trial mode, the amount of resources available is fixed and cannot be adjusted.
