Hidden ESSIDs and Android does not connect?

Hi guys.

I have 22.03.3 on 22.03.3 and am seeing something weird.
If I hide a wifi - so far tried Qualcomm Atheros QCA9886 802.11acn interface, in case it might matter - a wifi to which my smart phones connected just fine, then I forgot the wifi and add anew manually and this results in a failure - usually with message like "wifi was not found".
I say it's weird because my Fedora connects to that same hidden wifi, also set up manually, just fine.
Also! Android fails to connect to that wifi even off the QR code generated on Fedora.

I wonder if anybody seen this/simillar misbehaviour and/or would be happy to share any thoughts.
many thanks L.
