Hi,
there is still at least one old textdomain that isn’t working. In file single-event.php in folder src>views>pro>map in row 71 there is the following line of code:
<a href="<?php echo esc_url( tribe_get_event_link() ); ?>" class="tribe-events-read-more" rel="bookmark"><?php esc_html_e( 'Find out more', 'tribe-events-calendar' ) ?> »</a>
I think it should be:
<a href="<?php echo esc_url( tribe_get_event_link() ); ?>" class="tribe-events-read-more" rel="bookmark"><?php esc_html_e( 'Find out more', 'the-events-calendar' ) ?> »</a>
