If your trial is about to expire,consider converting your trial to a subscription. Your software shows the number of days before the trial expires. You can’t extend that trial period, but you can keep using your software by getting a subscription.
For short-term needs, you can get a monthly subscription and turn off automatic renewal. See Cancel a subscription.
Note: If you use a collection, the number of days remaining in a trial is different for each product in the collection. When you start the first product, the trial period begins for only that product.
