This started happening to me too. First on my iPhone, and it became so bad that regrettably I had to change my default browser app to Safari again. I'm sad to see that my browsing is now 10x faster and more reliable and thus enjoyable.
Now it starts happening on desktop as well. It's becoming so bad that I've stopped recommending this browser. I have to restart it multiple times a day, sometimes per hour, on ALL my devices.
This happens since a month or three.
