How do I get my tabs to stay open for next day?

For Windows 10, my GL tabs used to stay open for several days. Now they close every other day, and I have to re-open them. It's difficult to remember where I left off.
And sometimes it takes an hour for GL to open. Once last week, it never did open.
I don't remember any of this ever happening on my Iphone.
Is there something I'm doing wrong, or something I need to do?
Thank you for your attention to this problem.

That is a little unusual. If you are logged in then those tabs should stay there indefinitely. Taking an hour for GL to open is also very unusual. It sounds like the app is having trouble writing the files it needs. Any chance you are using a VPN that you may need to give the app permissions from?
