 * Dear Wprus developer,
 * I am sorry to report that I am experiencing a problem synchronizing login state
   across a couple of sites. I believe I have read all the relevant threads on this
   forum, and gone through every item in the FAQ. I have taken to testing the issue
   on a couple of newly-installed, vanilla test instances, and the problem is still
   occurring on my server. Here is a bit of information about environment and steps
   I took:
    – Installed two instances of WordPress 5.7, with default English/US 
   locale, running on Nginx, MariaDB and PHP 7.4, with TLS enabled. Both instances
   are publicly accessible. – Installed Wprus v1.2.7 as the only active plugin. –
   Took care to create remote site entries properly in both instances, checked every
   action except ‘create’ in one of the two directions (incoming on the first instance,
   outgoing on the second one), and double-checked encryption and signature keys.–
   Set permalinks structure to ‘Post name’. – Hit every ‘test’ button on both sites
   and got a successful result. – Enabled logging. – Created a test user on site
   A. This new user account is correctly replicated to site B. – Logged in with 
   test user on site A. Login state is not synchronized to site B. Log entries on
   site A seem normal (Login action, renewing token for site B, Added <URL> async
   URL in admin_footer. Log entries on site B are as follows:
 *     ```
       2021-03-23 21:21:41 - Info - Token created: site https://siteb.tld/ - action "Login"
       2021-03-23 21:21:43 - Success - Access granted
       2021-03-23 21:21:43 - Alert - Login action failed - received invalid data.
   
       		Array
       (
           [data] => 
       )
   
   
       2021-03-23 21:21:43 - Alert - Login action failed - incoming login action not enabled for
       ```
   
 * This seems so blatant a problem (a full empty data structure) that I would guess
   it is in fact a benign issue. Yet I have not been able to troubleshoot this on
   my own. I hope you might be able to help or point me in the right direction. 
   Meanwhile I will keep looking into it.
