First of all sorry for my bad English.
This is impossible to play like this. I would have already unistalled this game but there is something that's just preventing me do not do it :D
Hardware: Samsung Galaxy S7 Edge SM-G935F using 10 megaByte/s WiFi connection and sometimes 300 kiloByte/s up/down mobile connection.

1) The famous Hog Rider glitch! Basically Hog Riders are sometimes ignoring defensive buildings and go straight for the Crown Towers.
2) Weird notifications. As example I got Magical Chest at day 1, I opened it and received the cards at day 2, then there's game notification at day 3 telling me that my Magical Chest has been opened! *Yay did I just got MC from nowhere?? .. Oh no it is the old one that I have already opened.*
3) Connection problems (Only in Clash Royale). This has been happend alot to me lately. For like 15-20 sec I'm unable to do anything in live battles, just watch how enemy is three crowning me.
4) It may be connection problem too but.. Sometimes I see that enemy troops or buildings multiply. Luckily for maximum 2 seconds but this is so scary when there's suddenly 2 Minion Hordes popping up near your towers :S and then half of them disapear.
5) Then there's something wrong with troop selecting. It deploys different troop other than what i chose to deploy.
6) As example enemy troop is damaging my Crown Tower while enemy troop is getting damage from my Crown Tower and my troops, when enemy troop is on critically low hp then my troops(which did more damage than CT did) just randomly leave enemy troop and it got off another 1-2 hits which almost took down my CT. Shortly: While troop is on low hp then enemy troops just start ignoring him.

Supercell, please fix this or give us advice what to do about it.
