The new interface in Yahoo mobil and its new update is a disaster. One of the most usable things are email notifications. Before one could put the own notification and that activity has been removed, they only give the mandatory option of those provided by Yahoo that are first very bad, second their sound is very low and third you can not put for each email a different notification to identify by What mail is being received. The sound that they force to put is only for all the emails that one has added in his cell phone. Every time they put an update or change the interface instead of moving forward, they do not make a good improvement for the user. Put that notification activity back so that the user can choose a different one for each email that Yahoo has added to their cell phone because that way they will not succeed in their progress. They go from bad to worse and do not fit the use of users but theirs. They evaluate their programmers because they imply that they are not fit
