I have had a resolve dropper post for about a year now and have had the exact same experience as you. Rebuilt it when new because of the squish and then still had issues but this turned out to be the fact I store the bike vertically that caused issues. But the post not always fully returning is a hassle and particularly as it’s an intermittent fault is somehow more annoying. The post is beautifully made and the customer service from Wolftooth has being exceptional but it’s still not as reliable as my old brand x post that cost a quarter of the price
