"How to solve this problem"

-------

Update your iPhones:

Check this iPhone 7 for updates. As it reads: "[...]you should be using and iPhone that runs on iOS version 13.4 or higher[...]". Go Here: Update your iPhone, iPad, or iPod touch - Apple Support

Important:

Back Up First: Be sure create a back up your iPhone prior to performing an update, that way you have something to restore your iPhone from, should anything go wrong afterwards.
