After more struggle I found the way to override globally block queries:

/Newspaper/includes/wp_booster/td_data_source.php

static function &get_wp_query ($atts = '', $paged = '')

Function name above return queries for all blocks, so by setting condition in this function served my purpose very well.

Sorry for posting but its solved for me now.

Thanks!

For details that my query get modified as required ie: post tag filters get passed but it does not effect top grid on category pages:

In above screen shots we can see that post_tag filters are working as required in query. Please suggest.

Thanks!

Example of the menu working on pages other than the frontpage:

It is not a caching issue. We have explored that possibility carefully and caching is currently turned off.

It looks to me as if the frontpage uses another header template than the other pages, i.e. it uses parts/header/header-menu.php while other pages use parts/header/top-menu.php and the code is slightly different. So perhaps there is some issue with header-menu.php which makes it not recognize the menu…?
