This popup was somehow shown. When working for my previous firm they did NOT have the paid version. It then had as a consequence that everything older then 3 months or so was not shown and that search was limited. Current firm does have a paid version and we use it as a knowledge base to find things back - basically the memory of our team. If you are indeed using the unpaid version you might consider upgrading, though I have no clue how expensive that would be!!! I've dug in your slack channels and there is a wealth of information here!!!
