Thank you, it didn't occur to me that the atmosphere could be an issue.
But that could definitely explain why I couldn't get a sharp shot even on stationary subjects/objects at a far distance, especially since I did get sharp images once I got back home with the same settings and focal length. Thank you!
It wasn't a particularly hot day though. Clear sky, about 24-25 degrees (Celsius) on a fairly large open mangrove area, but still in a fairly urban environment.

So one question on this then.
Do cheaper lenses like the Tamron 150-600 g2 get more affected by the air quality than more expensive lenses, such as the Canon 100-400 mkii?

No.  It's about distance.  600mm only means more distance if it makes you step 600/400 times as far away from your subject.

or would have I encountered the same issue with the 100-400?

Same air?
