Saving as ai (adobe illustrator) file

I am saving as ai (adobe illustrator) file and suddenly I am required to login to Adobe creative cloud. Is this a glitch. If I don’t sign in, I can not export my file to a folder. Anyone else having this problem? I have been doing this for a while now and never had to sign in.
Please help.
Thanks, paula

I would like to know if there is a plan to bring .ai exporting to macOS? It seems like there are many features exclusive to iOS. I would love to keep using this program exclusively over Adobe products, even if I have to pay for pro features. Thanks.
