The colourcode on signs do not work normally after the recent update since 1.16.220. Normally before the update, type §1 or §a makes your text to become another colour. However, after the updates, typing all §(numbe 0~9/letter a~f) no longer gives a sharp change in colour. The colour change in words became dull and it is unable for us to tell the difference even between words in black (without typing §) and yellow (normally appear with §e). It is so hard for me to play since me and my friends usually type in different colours to show who typed the words on the signs. Since adding our names in front of our dialogue would probably make us use more spaces and signs finish our conversation, I definitely hope that you could look into and fix the issue so that we could enjoy playing MCPE more than every previous moments with the new blocks and functions. Thank you very much for your attention.
