I have the same issues, if i disinstall the app it will start, but if i cose it and reopen it it will not load correctly. 

I have the same problem. I uninstalled it and installed again. Then at the firt time it isOK, but at the second time closed down again...

I got this answer: 

Hello!

If you cannot log into the game or are experiencing performance-related issues, please try one of the following workarounds:
1. Change your connection method or use a VPN service to switch your IP address (e.g., Turbo VPN for mobile devices).
2. Run the game on your PC via Plarium Play launcher or use a different device: 

So they don't care about my main gaming platform (smartphone) and suggest (force???) me to use other platform, eg. PC????? Whaaaat? Saying that, if you want play Raid, buy a computer? 

Hay Plarium! I had no problems before version 4.0. I've played Raid since 7 months. You made a bug, and to solve it I have to buy a computer? C'mon, don't be silly...

Same problem here

I do have the same problem. Told them that i cant play on my PC instead of my phone and am waiting for an answer now.  

Let us know please if you get any answer. Thx
