Hello there,

Unfortunately, we cannot get that permanently checked due to user preferences as well as regional policies.
If this issue occurs again let us know.

So far, the "remember me" trick seems to have worked.

I don't ever tick "remember me" because I use Chrome to remember my passwords, so I thought that would do the trick, but actually ticking the box has helped so far ... at least for the past three or four days.

Thanks!
