Good morning @Gbyceng1!
If you're running the most up to date OS version and reinstalling doesn't help at all, we'll have to escalate a ticket to have the issue investigated further. Please PM us @CommunityHelps and I will get the ball rolling for you.
If you're not familiar with how to PM, please follow this link for instructions: http://communityforums.rogers.com/t5/blogs/blogarticlepage/blog-id/CommunityBlog/article-id/535
The issue describe is the identical one to the one under the Oreo and MyRogers that you posted @57
I have a ticket in with no response at this point. The only predictable way I have found to make it crash is to forget to log out and close the app via the x in the running app section of the OS home pages - OS 6 on LG4, last resease of MY Rogers March 21, 2018 version 3.9.8
If I forget to sign out, and just close the app - I don't have keep me logged in set on - it goes to the blank page and a sign look back to the same page.
I then have to uninstall it and reinstall it.
All individuals should have this escalated to second level support if it repeats after a reinstall - it is well reported on Google web page and hear now - it is time to get a white board notice out that the issue is known and we will open a ticket.
I have worked with various trouble shooting and through day, and definitely, if I sign out, I am fine to reopen it - so for now, I try to remember to close from the app, not let it sit running in the running apps page and closing from there. It always fails.
Hope my trouble shooting helps.
