Every so often I jump on a public wi-fi when I'm at a school or doctor's office. When I leave the public wi-fi and go back on my phone using wi-fi at home or cellular data, all of my Chrome tabs that were open previously are gone. I recently had 75 tabs open and all disappeared. Chrome then opened a few tabs that were open a month or so ago. This happens somewhat frequently and is very annoying. Any idea why this happens and how I can open all of the tabs again without manually opening each from the history?
