Love the method and content so far. Was, however, disappointed that they charged me immediately rather than at the end of the 7 day free introductory period, which left a bad taste. Good thing I like it otherwise would have angrily asked for a refund, but as I said, it left a bad feeling nevertheless. In response to developer: I did not use different Apple ID’s; I only have one. Sounds like an issue between Apple and the developer that needs ro be resolved so that it does not happen again? I do appreciate your responding, however. 
 We are very sorry for this unpleasant experience. According to Apple App Store's policy, the 7-day trial is indeed free, and this may have happened because you used different Apple IDs, so the free trial opportunity appeared again.
