This is because avast does not have the QA department that would test the products before releasing to customers.
As I mentioned in other topics, adbloc no longer blocks the ads (the advances settings are no longer available, because avast believes that customers are too stupid to use them), connection with LTE network causes performance deterioration, now there is no more sound, my favorite web app for public transport idos.cz visually breaks, the free antivirus quite often does not react on button clicking (including Restart after installing a new version of the app), etc. I tried to report all issues here, to the emails or via the form (it it works).
I suggested to establish a standard QA department a few years ago to one of their managers who was available during their open house day at the HQ, but they just do not care about the QA at all.
