Signal is working on a way to sign up without a phone number. The feature has not yet been officially confirmed, and it is not yet known whether it will be available to all users or in what form.
People dont WANT to you to find them by phone number. Its not a bug and its not happening randomly, people are just enabling the very good setting that prevents others from finding them by their phone number.
Whether or not you can find someone based on their phone number is based on a user setting. Each person chooses whether or not they can be found by their phone number.
Go to Settings - Privacy - Phone number.
Really though, this is an excuse more than a roadblock.
I find people oddly resistant to an additional message app, yet they gleefully download a new app at every carpark they visit. People are odd.

They added a username feature a long time ago that makes finding each other very reliable.
