I migrated apps and settings from my old Android phone to a new Android phone, and now it seem like Join can't distinguish between them as Join-devices. The new phone showed up in the device list in my browser, but my old one was gone. I tried to send something from my old phone to this computer, and the old phone replaced the new phone in the device list. Same happened when I used Join on the new phone, it replaced the old one. I tried to uninstall and reinstall Join on the phone not showing up at that moment, but it still replaced the existing instead of being added as an additional device. I also tried to uninstall Join from both phones, and delete the one device showing up from my list of devices, and then install one at a time. Again, I was not able to add them as separate devices. The second unit I installed Join to just replaced the first one.
