Tinder logged me out, unable to log in?

I registered a week ago at Tinder not via Facebook, but via the mobile number in the app by phone, now I open the app and am suddenly logged out. I have the options to log in via Facebook and the mobile number, but if I enter my number, the code will not be sent to me. Have tried it already with the voice code, does not arrive. On the computer I can choose to get the code via WhatsApp, which then worked. But unfortunately I can only access Tinder from the laptop, which is pretty impractical. How can I log in again on the phone?

Try reinstalling the app, sometimes that helps.
