User Sessions not expiring at the end of Userman Profile/Limits

We have configured the Hotspot / Userman

We are able to login as a user we have created and assigned a 5minute profile to it.

Name - 5m
Name for Users - 5m
Validity - 5m
Starts - at first login

Added a limitation -

Uptime -5m

After 5 minutes of being connected the account does not expire and we are able to continue using it.

I have googled this and searched the Mikrotik forums with no joy.

Only thing i have seen that could help is COA

We have tried enabling COA support in the router details section and tried a 5m user again and this still did not work.

This is now unticked again.

Any help would be greatly appreciated.

This has been resolved by enabling COA and setting it to 3799 in userman (originally 1700)
