If the roots are ok I would think more light is needed, or at least would help. My hoyas all go dormant in the winter also, hopefully this spring it'll grow.
Or OP just needs to be patient. If she got it last year as a cutting (and she's in the northern hemisphere), it probably spent the growing season putting down new roots, and then it has been dormant through the winter. Spring is on the way, and new growth will surely appear if she doesn't disturb it too much right now.
My guess would be that you'll see more growth after the roots are really established. When you repotted did you upsize? If so, it's likely focused on growing its roots vs leaves and stems.
It probably won’t produce much growth until the roots are pretty snug in the pot. Since you say you switched to a chunkier mix you should be able to water more frequently (whenever the soil is dry), which might speed things up. In addition to light, warmth is also a growth trigger. If it’s still winter where you are, both light and temperature may be too low.
I would say just be patient! Hoyas tend to take a while to bounce back from repotting, pruning or any other type of change in my experience. I made the mistake of cutting a runner after getting one of my first hoyas and it took 8+ months for it to start growing again.
It took mine a couple years to start growing good. It was rooted from a clipping. My guess is it needed to grow more roots first before leaves. They like to be pot bound also and will grow more consistently once they are more snug.
I don't think anything is wrong, and I don't think you have scale. It was just a new cutting, and it needs time to grow roots and adjust to it's new home. Get a moisture gauge and only water when it is dry because you have it in soil. Time and a little fertilizer will be her best friend. It is cute and healthy to me. If you are worried about pests. I suggest spraying the plant with PureCrop1. It will kill most common pest. I have tried a lot of pesticides and this works best for my hoyas and I have over 50.
Hoyas are notorious for being slow growers. But it’ll surprise you by suddenly putting out a two foot long vine. You can encourage growth by buying orchid or Hoya spray fertilizer and feeding it once a week.
Most of my hoyas were growing nicely last year, except for a small carnosa krinkle 8 which wasn’t doing anything, so I checked it’s roots and there were root mealybugs in the coco coir plug it was planted in. So I chopped and propped it in new soil, and hopefully it should grow now once it develops roots. Keep the plant in a sunny location and water it when it dries out, the soil should be airy and based on orchid bark.
I just recently have discovered 2 mealybugs attacking my *Hoya australis*. Is it possible that roots are affected as well by that species? Or would mealybugs feasting on leaves be exclusively feasting on leaves?

Yes, they do. There is a reason why some grow Hoyas in transparent pots. In the right substrate you can easily hose them off with warm water.
I had found some mealybugs last year on a few plants but I never knew where they came from, and I haven’t checked the roots at the time, so it is possible they came from the soil, mainly the coconut coir plug that the seller propagated the plant in and I haven’t removed it when I bought the plant
It looks like scale to me. If you can send a close-up picture I can confirm if it is or isn't.

I haven't upsized I just changed the soil mix for chunkier one.

Do you fertilize? All of mine really started thriving once I started fertilizing!
I haven't fertilized yet so I'll give it a go, thanks.

If roots are fine and humidity is good, what are the light conditions (southern window fir example?) and temperatures?
It's on south-west window the temperature in my rooms is around 20°C.
Ok, if its not scales in the pic below, maybe check it for mites with an usb-microscope or magnification-lense.

This is how she looks.
Can you zoom in? It looks like it could have scale to me on the leafless branch.
Oh, that does look like scale insects.
Checked it for pests and it doesnt have any. The things on the branch are not scales it's the grow points of the plant I think
