Problems with Evident document uploads?

Is anyone else having problems with the Evident app not working? When I press the upload button, absolutely nothing happens. I might as well be pressing on my desk.

The only thing I can think of is that my phone is not the newest. I’m running Android v12, because that is the most recent that will install.

I wasn’t impressed with the support on this issue, and that I’d have to contact Evident, who tell me someone will be in touch in a day or two. Not a great initial first impression, overall.
