With version v15 , all my motion graphics where suddenly offline. I upgraded to v22 and believed that this would solve the problem. However, now I cannot load any motons graphics. When I pull them into the timeline, they are stuck at 15%. I tried reexporting the motion graphics with After effects 22 but this didn't work.
I used an older version of my file with version v15 and was able to find reconnect the files. I can also pull motion graphics into the timeline with v15.
