MAC filter option is not working properly on vodafone router

[LeoStas]

Hello! When I'm activating MAC-filter option on vodafone router it works fine for some time (up to a day). But after this time my devices refuse to connect to WLAN. They get reconnected immediately after I switch off MAC-filter option. So it looks like this behaviour is related to MAC-filter option. Seems like a faulty software on my router. Can this be fixed permanently?

A bit of context: WLAN name is hidden, MAC addresses are static on devices and don't change, all addresses are registered on router, both 5 and 2.4 Ghz network is turned on, band steering is on.

Looking forward to your reply.

Hello LeoStas,

unfortunately you haven't told the other users which device you have exactly.

But you are welcome to have the router checked. Please get in touch with us via our contact channels.

Hello!

This is Vodafone Station, 19.3B70-1.2.49.

I wish I could contact you via phone, however the bot that answers the call doesn't have English language option available (quite not client oriented, tbh) and I don't understand what it's asking me, so I didn't make it to a live agent.

And I'm trying to connect a laptop and a smartphone to the Vodafone station.
