New feature-feeding berries remotely- may not be working well

Let me know if anyone (people) successfully beat legendary ones!
Feeding berries remotely may work only in short distance but not if you are a couple blocks away ?
Still crashes often during/after accessing the gyms. Hoping the issues will be resolved. ?
The movement during fighting at a gym has significant improvements (dodging attack).?
