Thank you for posting and welcome to the Bose Community. Sorry to read that you aren't able to connect your Huawei, let's look into this further.
I would recommend that you start with ensuring that both the mobile device and Spotify are running the latest software versions, this will allow us to ensure that it's not a compatibility issue you are having.
Please, can you also ensure that your Soundbar is running the latest software version by following the steps listed here.
If anyone else has had a similar issue with their Huawei please do let us know.
