Hi @dovanluyen123,
(Although the plugin is translated into multiple languages, support is only provided in English.)
Translation of your message:
The buttons on the payment page are buggy on Mobile making it very difficult to press. It takes several times and sometimes dozens of times to press so I had to turn it off. All the buttons like: payment, next step, return, shipping,….
Usually when this type of problem happens this is related to a compatibility issue with the theme or another plugin you might be using on your website.
Since the plugin is currently disabled on your website, we are unable to evaluate it on your website.
1. Could you share some screenshots of the issues you are experiencing?
2. This error is probably a conflict between plugins, so it would also be helpful if you could run a plugin conflict test to find out which plugin or theme might be conflicting with Fluid Checkout.
Basically, you temporarily deactivate all plugins except for WooCommerce and Fluid Checkout, then re-activate each plugin one by one until you find one that causes the issue. Ideally this should be done in a test/staging copy of your website. You can find more specific instructions in the article below from WooCommerce:

Best,
Diego.
