Installed on a Samsung Z Flip. I'm able to log in without issue but other than that, it's a complete waste of time and resources on my phone. The screen looks as though they took a webpage and tried to cram the entire view on a smaller screen. One big help would actually have the ability to send and view messages which is non-existent in my version. Click on Contact Us and get a page with phone numbers and addresses. No way to send a message. Bad thing is I got an email stating I had a new message and had to wait before I got home before I could view it. Click on "Send app feedback" and it wants to open Gmail or Outlook. I use an app for my primary care physician and it allows me to everything as their website. Don't waste your time. Not worth the effort.
