Craftkings review for OPTIS Product Options, Variant

NOTHING WORKS!. i've spend months adding the options on products and now everything is down. app glitches on a daily basis. option disappearing , showing on different products, prevents customers to add to cart and so much more. Last week only our sales dropped from £3000 per day to less than £1000 due to this issues. DO NOT TAKE THIS APP IF YOU WANNA KEEP YOUR BUSINESS UP AND RUNNING
