TD Bank has run into a number of issues since updating their online banking and mobile app experiences; customers have had issues accessing their accounts, transferring funds and paying bills; the issues point to a problem among banks as they try to figure out how long new product releases should be tested before releasing to market; the bank has tried to ease customer complaints by responding on social media but that has only made problems worse; with the amount of competition for customers increasing in banking the traditional players will need to better prepare the beta testing phase.
