Today the game became too slow during loading and everything ingame. I also cannot retrieve my free boosters. I wait several minutes then the game states there was an error. I have to cancel the transaction then. Tomorrow I should retrieve 3 free boosters as monthly reward. I really beg you! Let it work!
I am on Android.
Same issue. I bought karn. Can level him up. After i stop spending runes it times out and puts him back to lvl 1.
Same here
EDIT: just realized I get the same issue with the booster too.
Same issue on slowness and boosters.
NoP - match begin/end is very slow with lot of “cancel/retry”
Training Ground - slow but playable
free boosters - almost impossible to collect - I was able to get one or two during whole day
Same here. I think they just slow down a little, because of rix and dom came so fast after ixl. 
Several people have reported similar issues after buying Karn. Anyone having these issues without Karn?
I do not have a Karn, but I do have serious problems with playability 
To add: yesterday and last night after the update (and purchasing karn) the game worked fine. Constant SWW screens and the spinning circle didn’t start until today.

On android I can’t open the inbox. It seems like everything else works, except the inbox and vault buttons. (But I can get to the vault through the menu)
this morning it was slow , but it loaded. After work my first match didn’t load in Nodes of Power and I lost the match. Still waiting for a response from my ticket for losing 400 pink gems from the elite pack from loading problems. Basically unplayable now. Its not a constant bug , but it seems random throughout the game. My free booster worked this morning after not working yesterday with error , but its back to the error again.
