Bedrock Realm Bug with Chat, Sign, Books

Chat. sign. and books are broken in realms:

Chat is delayed in realms and only works for certain time(otherwise message sent while the chat is delayed gets sent when chat start working for short time), note that during only that time (when chat start working normally) you can write on books and signs otherwise they don't work as well(example: when bug is ongoing and you write something on sign and relog text disappears, or if u dye/glow ink sign after writing something while bug is still going the text disappears right in front of you, and booknquill don't work at all while while the bug is going)
