One thing at a time
If you noticed that your kitchen sink tap was dripping, and then a few days later noticed that your bathtub drain was slow, would you assume the two problems were related?
Could the two of them together indicate that there's some larger problem, somewhere, that you should be worried about? What else might be about to go wrong?
Your answers will depend on how much you know about household plumbing.
But whatever you might believe, one thing is for sure:
If you want them fixed, you'll need to pick one and work on that first. Then fix the other.
Here's the thing:
In complex systems like CiviCRM, data and functionality can be connected in ways that are sometimes surprising.
And when you encounter a few surprises in a short time, it's tempting to feel overwhelmed, as if "everything" is going wrong at once.
Chances are, not everything is going wrong.
But either way, if you want to address those surprises, the only way is to pick one and deal with it first. Then pick another.
Even if they are interconnected, you still have to deal with them one at a time.
All the best,
A.
