Help for Aimeos

I am using Aimeos Typo3 shop extension for building a shop website. But I got stuck at one point. I need to have the language and currency to be translated. I have two languages, German and English. At first click, it is working. But for the next, it is not. In one article, I read that "We would suggest that you don't use the Aimeos language selector for TYPO3 as it's better to use the native TYPO3 mechanism. It's primarily for the other Aimeos integrations." Is this true?? Whether I need to use Typo3 language selector option? Or whether I missed any more configurations?
Expecting a reply. Thanks in advance

Yes, that's correct. To use Aimeos as part of a TYPO3 installation, you have to configure the languages in TYPO3 (config.language) and use the TYPO3 "L"-Parameter to switch between them.
