1. System always hangs , especially while updating multiple PNs. Then once it is OK , the last PN may not have been updated in the system correctly.
2. Sometimes , even if you enter the User name & Password correctly , the system will show ‘Invalid user name & password’.
3. Sometimes , when we get access into the system , no PN will be displayed.
4. Sometimes , everything seems to be OK , but actually the PN may not have activated correctly and no error message.
