If you're using a paid trial, or paid plan on the SuperLemon WhatsApp app, and you want to downgrade back to the free plan, it's really simple and will only take you a minute.
Open the app dashboard on your computer or phone browser.
Navigate to the Pricing page by clicking on "Pricing" option below "Help & Support" in the left sidebar. See screenshot below.
Click on the "Downgrade Now" button on the FREE plan card, and you will automatically be downgraded to the Free forever plan.
Please note: Paid trial plans are for 7 days. If you want to downgrade and not pay the monthly subscription fee, you have to downgrade before 7 days are over.
