Thank you, that really helped. Meanwhile, I have researched the problem and I came to a sad verdict. Those necessary apps like the one mentioned above are having more problems with the optimization and adaptability because of the fact that there are more money and people involved in apps like https://clubvip777.com/web/empire777/
than in really useful apps. That is sad, from on point of view, but fair from the other, because such apps like the one mentioned before are more profitable and also more downloaded, so more money, more quality provided by the developers. The things are that simple!
