Subscriptions errors :(

Hello,
we are selling a access to a specific Joomla group. Everything works ok, but:

1) after processing electronic payment - even when user (who is logged to his Joomla account) is refreshing website - he cannot still see the buttons for his new group access - he needs to logout and login... it is not user friendly - how can we manage to change it??

2) When subscription time is over - the user still see his access to a private group (it is visible in the Joomla user groups too) - but when he tries to access specific private menu element - the information 'error, You cannot access' is visible :( and finally then - his access groups are changing on the backend. Can we make it MORE USER FRIENDLY - this should work flawless, now it is totally CLUMSY :(

3) Subscription 'renewal messages' aren't delivered to the users (in the setup time delay on subscriptions)

Please help!
Kamil
