How Group or locking layers
How do you lock or group all the layers in your image? I've read forum that said you have to click on the 3 dots. I do not see any three dots. Another said to select layers from the image and not layer icons themselves. Doesn't work. Another suggestion was to try a different browser. I tried Chorme and Edge. Other suggestions were click on layer and hold shift or ctrl A... these don't work either. I have a simple 3 layer image that dreated and now want to crop/resize... but can't lock the layers. Seems like a lot of people are having this problem. Where is this function?
