The removed or new movesets will not change the Pokemon players have. However, they will alter the creature players get in the future. Also, eggs that players got before the patch will have pre-patch moves when they hatch.
After the change, Gyarados is not a powerful Dragonite counter, according to a Reddit user.
The sudden influx of rare and uncommon spawns in all areas is the greatest change to the game. Suburban as well as rural areas are the most impacted by the change.
Also, according to reports, region locked Pokemon such as Mr. Mime and Kangaskhan were appearing with higher frequency on their continents.
In mid-July, the game reached peak 'daily active players', at 45,000,000, and has seen a drop in the numbers since, according to a BGR report.
Players have experienced game-breaking glitches as well as server crashes that made the app hard to play for long stretches of time. Pokemon Go has been running smoothly during this month.
However, the nearby tracking feature is still not functioning as it was when Pokemon Go first released primarily due to a bug. The developer has not been able to fix the bug yet.
Meanwhile, it is said that Nintendo will launch Pokemon Go Plus in September that could provide a big boost to the popularity of the app.
