Hello Oleg!
Thank you for your feedback. The fact is that the LinguaLeo store prohibits the operation of our extension on their site. On the sites of such stores, the extension will either not be activated, or it may work incorrectly. To get cashback from the store, you just need to go from our website to the store directly.
You can see on the page of each store with which we cooperate, information about whether the store is available in the extension.
If you have any questions or suggestions about the work of the service - write. Have a good day!
Sincerely,
LetyShops team
