We are trying to have the flex prompt the user to enter a tip and it seems to have stopped working when our devices were updated about a month ago. I have checked the settings per this thread
https://community.clover.com/questions/10257/why-d... and they are correct. Is there something on your end that needs to be enabled? We are using the v3 android sdk and are setting the tip mode on the request. Our serial number is: C041UQ72820654
thanks
