Getting signed out

[partfinds]

What is the Ebay option to keep you signed in when I am getting signed out every couple of minutes?

I am not sure if Ebay did something in the past 2 hours but I am kept signed in . I hope it will stay like that.

Yesterday was kicked out twice and today I am back to being logged out more often.

I am still having issues with staying signed in. On Sat I was signed most of the day. On sunday , I was getting signed out every 10 min. Today I was signed in till about noon and now I am back to logging in every 15 min. 
every time I go to read something somewhere , get notification from Ebay and I have to sign back in.
