The long load time was a recognised problem in an earlier version of Tinder for Android.
If you're using an Android device, I strongly recommend search the Play Store for a more current version of Tinder.
Upgrading should fix this bug.
If you're on iOS or you've tried updating Tinder and are still having problems, then I would recommend the following steps:
- Make sure no other apps are running in the background
- Turn off background app refresh for any apps that you don't need.
- Ensure location settings are turned on for Tinder.
- Close the app and then relaunch it.
Hopefully this should solve your Tinder problems, now you just need to find a few matches to flirt with!
