If you have a Pro subscription on Tickertape and still see a "lock icon" on pro features, just check if you are logged in using the correct email address. To check this, follow the below steps -
Step 1 - Go to Settings from the top left sidebar.
Step 2 - On General settings, you will see the primary email as the email you have logged in from, and below that, you can see plan details. It will show you your current pro plan and its expiry or renewal date.
If you don't see Plan details below the primary email, it means you have logged in using a different email address and your pro plan might be linked to some other email. Try logging out and then logging in using the correct email to access the Pro features.
Step 1 - Click on settings and go to Your membership.
Step 2 - On the "Your membership" section you can see details of your current plan and its expiry or renewal date.
You can write to us at firstname.lastname@example.org if you still face any issues with your Pro subscription along with the details on the transaction (date, time, and mode of the transaction).
