What are the common limitations of using a free Blogger theme compared to a premium or paid one?

Free Blogger themes often come with certain limitations compared to premium options. These can include less frequent updates and support from developers, fewer advanced features (e.g., complex shortcodes, multiple layout options, dedicated e-commerce integrations), less unique designs (as they are widely used), and sometimes less optimized code leading to slower performance. Free themes may also have mandatory footer credits to the designer that cannot be easily removed without breaking terms of use, and might lack the extensive documentation found in paid themes.
