I tried a little more and found a reason.
In the Wallets frontend settings, I left the Live polling settings value blank instead of ‘0’
( Both ‘Coin info poll interval (minutes)’ and ‘Transaction list poll interval (minutes)’ ).
I changed the value to ‘0’ as instructed and the delay is gone.
When blank, there was a big delay when the user first joined. (only frontend)
Now that i have entered 0, there is no delay.
