Pronunciation exercise error

Issue is also with Portuguese (Portugal) 1 and 2 (I haven’t progressed any further).
Frequently, the Pronunciation mode will not accept the correct pronunciation. The problem is intermittent. When it happens, it will not even accept the pronunciation given by the Memrise voice.

Example, most of the numbers in the following lesson do not work:
Portuguese (Portugal) 2
5 - Fuel Your Vocab: Numbers

Huawei BTV-W09
Android version 7
Memrise app version 2021.10.8.1

For me, troubles with japanese. I am an actor and musician, I have a very good ear and pronunciation, and it is very frustrating to have a “not quite…” mention 3 or 4 /10 questions.
