Will my company's overall CTR drop significantly if I set a mobile bid adjustment of -50%?

Question

Yandex.Direct

Good afternoon.
There is a company without rate adjustments. The company has one advertisement with the key "Buy ariston boiler". 50% of impressions and clicks are from computers, 50% of impressions and clicks are from mobile. For 1000 impressions, I have a CTR of 20% (let's imagine that this ctr is also evenly divided by computers and mobile).
I decided to make the maximum mobile bid adjustment -50%, and now my mobile ad is showing at the very bottom and has 0 clicks on it over the same period.
QUESTION:
It turns out that now with the adjustment, my total CTR for the company has become 10% - and I have to pay MUCH more? (because 10% is really low for this query).
QUESTION 2:
If the statement above is correct, I need to decide whether to pay less for mobile clicks (low conversions), or pay more for desktops only (but high conversions)

Answer 1

CTR is calculated separately for each block of positions and separately for each type of device. So if your ad is truly relevant, interesting, and well-distinguished from your competitors' offerings, then you will continue to receive above-average CTR for that combination of positions and devices, and thus also receive lower bids.
