"Too many connections devices" when signing in

I have reset my android device 2-3 times. Before this I was logged in to my account having data on WARP+. Now after having hard reset the device when I try to log in the app shows “too many connected devices”. One is my PC, 4 others are the same phone I have reset now. On PC there’s no option I can find to remove the other devices so that I can connect to my phone again.
This is a big problem as I had a lot of data on the account and now I can’t use it on my phone even though I have the key
