"Experiencing large influx of network errors since gym update"

#PokemonGO: Ever since the new gym system was released, the performance of my phone (Xperia Z5 compact) has fallen off a cliff - I am struggling to play the game for more than about 30 seconds without it grinding to a halt or erroring out. The game also takes typically 2-3 tries to actually connect in the first place - the map loads, but no pokestops/gyms/pokemon, and I have to restart and try again. This makes raids almost impossible - the 120 second wait alone is generally too long, and the game will freeze as soon as "GO" is displayed as the battle starts.Obviously this is extremely frustrating, but I came here to ask if anyone else has been experiencing similar problems, and if they have found any solutions. Apologies if this is the wrong place for this post.Edit: as /u/moatmai pointed out, it seems to be affecting a lot of different phones. Is anyone with the same phone as me (or other people reporting issues) able to run the game smoothly? via /r/TheSilphRoad http://ift.tt/2timqn5
