When your Membership (PRO or UNLIMITED) expires, we not delete any Transactions. Your account is set back to FREE, which means you can not run any API or add any new transactions (max. 200).
When you renew your subscription either to PRO or UNLIMITED, you have to re-activate your API jobs so that they can run automatically in the background - you need to do this for each API page individually.
On every page please follow these instructions:
1. Click on "edit"
2. Set the API to "automatically"
3. Click on "update"
4. Click on "back to your jobs"
