Player visibility bug

in servers i usaually play pvp but its not abaut that i wanna say,1.20.0 came out but with a bug that players play on 1.19.xx version of bedrock are invisible for 1.20.0 players exemple on lifeboat is happing all the time.

and tha can be a vantage to 1.19 player but a disvantage for 1.20 player(and yes i seach if it was a invisility potion but close to none servers use potins,taht are feather servers)so yeah its a bug that came with 1.20 and effects about 1.19 players.(sorry if you dont understood because my inglish is bad).
