Boost charge broken since 2.79
Starting from 2.79, boost charge button sometimes charges only one resonator. On the next click, all resonators are charged as excepted. It happens randomly, I found no specific pattern to force / reproduce this bug, but it happens quite often to be noticeable and annoying. It may happen anywhere anytime, on both map screen and key management / remote charge screen.
It was broken in 2.79 and all versions up to current 2.81 are still affected. The problem was immediately noticed by other users in "Release notes" thread for 2.79 (both on Android and iOS) but nothing was fixed in 2.80 and 2.81. Until 2.79, it worked as expected.
Writing this as a separate report hoping that it'll get more attention than few posts in "Release notes".
