until you lot trashed it! Oh, the satisfaction of a job well done! 
Ibiza Not entirely the plant apps. Beginners can make similar mistakes to plant apps. The plant apps are basically image recognition "this picture has the same layout of white and green pixels as a picture on the internet that was labelled Sedum dasyphyllum" and beginners can do the same. "This is a small purple flower, it must be a violet" despite the fact the flower shape is wrong, the leaf shape is wrong and it's flowering at the wrong time of year. Neither plant apps nor beginners have the knowledge to say "this is clearly in this family, so that immediately knocks out a lot of possibilities"
So are people "learning" things from plant apps and therefore giving wrong ids? Or with the growing distrust of "experts" are people becoming (in this case unjustifiably) confident of their own knowledge and more willing to state an identification when in earlier years they might have kept quiet or been less assured? Or is it that there are fewer people in the community who can set them on the right track? - I learned a lot of flower names from my mother, and this wasn't at all unusual, but I think it would be unusual today.
I have been alarmed in recent weeks - I'm on a facebook wildflower group which includes as members some of the best botanists in the UK, the people who write the text books, the people who interpret the DNA and determine the classifications. Yet every time someone says "can you help with an id", someone pops up and says "you need to get [their favourite plant app]".
You're right, it's got a lot worse in the last few weeks. Is it lockdown? Lots of people going out for walks to green spaces that they've never visited before, and for the first time noticing wild flowers, and grabbing their phone and looking for an app.
The trouble is that most people hazarding an id for a plant they don't really know, will say "I'm not sure but ..." and you know to treat the id with caution. But plant apps don't say "this is 100% definite" or "this is a possibility" and people armed with a plant app will pass on an id as if it's definite.
