Signed up for the free 7-day trial, which automatically defaults to their "premium" plan for the duration of the 7-day trial. I am not interested in being on the premium plan on a permanent basis and would like to switch to the standard plan. Initial customer service inquiry says that subscriptions are managed through the Google Play store (true). But once in the Store, there is still no option to downgrade to the standard plan. Second message from customer services indicated that they will "check in with their technical team." If their promotional materials say I have the option of a standard plan OR a premium plan (but there is no standard plan), then this sure has the appearances of a scam even if the phone number is working correctly (it is). If you are going to offer two price points for two different plans, then both plan types better be available. Very disappointed in how this has played out so far.
