I recently went to your extension page in the official Joomla extensions directory (JED) and saw that there is information only about compatibility with Joomla 3 and Joomla 4, but I did not find information about the compatibility of your extension with Joomla 5.
I have a question: does your extension work in Joomla 5 without enabling the system backwards compatibility plugin or not?
please update your extension's page in the Joomla catalog (JED): https://extensions.joomla.org/extension/clients-a-communities/jomsocial/
