I just did some quick research and I can't find one credible source saying its a bad idea. Every oil manufacturer, plus popular mechanics said there's absolutely no issue switching back and forth. The only people I could find that advised against it were people saying "I heard it's bad" on forums. This is where most mechanics would fall as well. They do not know anything about the actual oil properties, they are just telling you what they heard or basing their opinion off a skewed set of data.
