My device is past rooted

Hi there.

I recently downloaded the version 0.37.0 of pokemon go which blocks rooted devices, but my device is not rooted and i am experiencing a issue that is a kind of "infinite loading", pokemon go just loads, not apear any kind of message at all and when i return to the version 0.35.0 works properly.

My device was rooted a while back, when i buy it, but is not now and is not using a custom room.

Anyone know something about it? Thanks.
