AVAST SECURE BROWSER Frustrating issues

Avast secure browser has too many glitches…
It is way too slow to load, particularly in bank mode. Also, while trying to type there is a delay the script being placed.
Updates to the browser have to be done manually; but dosen’t help anyway.

After contacting support I was told to uninstall and reinstall, ( support’s go to remedy with everything); didn’t work.

If this is what I can expect with the free version, why would I even think about purchasing the PRO version.

Any advice would be appreciated.
Thanks.

The lag in typing is the worst thing, I went to MS EDGE and there is no lag, When I first launch AV browser it works fine but after some use the lag kicks in.
