App or online this is horrible... Spent over 300.00 then the slot errors. Have to refresh and lost the pots i had been building. Email them get a bs story about do this in that to fix the problem. Still dont make up for the fact took all that money to build the pots. Sent picture proof and all they did nothing. I have made contact with BBB. See the responce... Was on wifi... So whats ur next excuse...
