When you downgrade your plan, you might find that you're asked to reactivate your plan in order to see your feeds again. This is because when you downgrade your plan, you might have more feeds than your current plan allows. If you wish to proceed without upgrading again, you will need to opt to continue without upgrading. This option will deactivate all your feeds and socials and you will have to select which ones to reactivate.
This screen will pop up when you log into your account. You will need to select the "Deactivate all social profiles & feeds and decide later" option.
