I downloaded apk from xmamager(not the latest version), I installed it. When I am trying to login using phone number and OTP, after Submitting OTP a popup of something went wrong came. I tried it multiple times and still the same issue. What is the problem?
It’s a bug, and you need to download an older version then sign in then update your app
I found a workaround for the same issue, first download the original Spotify from play store, open it and log in, then go to your file manager and copy the Spotify folder from Android/data and paste it somewhere you remember, then delete the Spotify, next download the Xmanager version and install it, paste the files you copied to Android/data again and login, it would work
Just add a space in your email before logging in. I was facing the same issue. If that does not work then type your password/email manually instead of auto filling if you’re using bitwarden or any other password managers.
There is no single solution to this problem. Failed sign in and “wrong password” error is a well known bug in xmanager.
I’m facing the SAME issue 
Use desktop first and solve the issue. May have to do a password reset. Once done, then move to your phone and continue the process.
Reset the password using web app and then login into application using vpn
I haven’t faced this issue.
I didn’t download the apk from XM instead I downloaded it from mirror link
Try that
force close and then reopen,youll be logged in
Are you using private dns?
What worked for me is I disabled supported links from the original Spotify app in the settings, while enabling supported links within the cloned app.
I try and fail to login using my username and password and I get an email from spotify that sent me a link that lets me log in that way and that worked for me!
Has anything worked for you?
Nothing working for me. How’s everyone doing it ?
I did this and changed my password and used a vpn too , it worked , yesterday happened again now it logs in and works but as soon as I turn off the vpn it stops working and goes offline
This, I’ve had the same issue. Download the APK from a couple versions prior, sign in and then update.
This worked for me thank you! I didn’t need to sign in again once I updated with the new one! 
This worked, many thanks
you sir are a gentleman, this worked for me after 2 days without spotify, thank you very much
Didn’t work. I installed spotify (pplay version), logged in, then tried to update with xm spotify, only to he shown some “package invalid” error.
Where to find the mirror link?
