I was using easyeda for the past two years so I became some what of an intermediate to professional in using it. I'm working on a project right now and I noticed that easyeda have a lot of bugs and the most annoying one of them is the autorouter feature is becoming worse than the previous versions since instead sometimes nets close to each other with nothing in between it does a long path to connect them in a few words in my entire PCB there is no single track that I will not correct.while previously it was doing a good job I had to only connect the ones that it couldn't figure out and fix a few ones Undo not working correctly sometimes the last thing that you want to undo stays and undo the things done before that when previewing 3D PCB it shows the pcb small and show the components far from it when you rotate a part the text jump very far away from the part when I preview as a photo the via drills doesn't show up if I'm going to list all the bugs I found I will write a full page how can I downgrade and use the previous versions of easyeda ?
