The app itself is pretty nice and easy to use. However, the support is crap. You can't contact them directly. You have to send a message in a chat box and hope they answer, which they don't. There's no email address or submission form.
Also, be warned, you cannot turn off Shopify's automated customer notification when an account is created. If you also set up a welcome email through Loyalty Lion, your customer will get two emails. It's easiest to forego the Loyalty Lion welcome email and just customize Shopify's automated email.
easy set up - we'll see, i'll update in a couple of weeks
Translations which you pay extra for, does not work on mobile devices. Issuing a ticket supporters do not make time to read entire ticket, and just closes the case... this is sad because it is a good system for loyalty... but the supporters are not serious if they don’t take the time to understand their customers problems fully this results in a lot of wasted time, trying to make supporters understand that the translations are not working on mobile, but works on desktop...
