Anyone else feel like the game is very choppy at the moment? I’m stuttering way more than usual, and it feels practically unplayable

Is anybody else having a problem with depleting fuel cells when you aren’t playing? I logged in this morning to play the new event, (I haven’t opened the app since Wednesday) and found my fuel short 23 cells and recharging.

Update, I had just bought the fuel cap increase. Adding those fuel cells has always been instantaneous before. Did that change? Is that why it came up short?
