As we have got a lot of support tickets regarding how to recycle or extend referrals, I have attached a screenshot of it.

You need to select the referrals you want to recycle or extend and scroll it down to the bottom of the page in order to choose between recycling and extending options.

Well, i want give little guide about manage rented referrals(RR'S)
For first: rr's - it's not real users, it's bots.
For good profitable try extend all rr's on maximum 240 days, price for each rent 1,12$
RR'S die after 240 clicks and need recycle them, but if you want make more profit, try recycle them into 24h, i mean 2-3h before restart server time and rr's make new ckicks before restart in that 24h = profit.
About autopay - i never use.
