You are only allowed 4 lines, so if you are writing more then it will be very little...
Here is an example of the 4 lines correctly, you, of course, can write more than this example on each line...( I'm just numbering to show you how many lines are being used)
Please help me with bakeries
Sushi and coffee
All hearts area
please and thank you
So if you are putting more spaces than those 4 lines or hitting the enter button too many times between lines then it will make it little and players can't read it...(I'm just numbering to show you how many lines are being used)
we see many players write something like this in their message bubble and then it is too little for their neighbors to read...
Please help with bakeries and coffee and hearts
thank you have a nice day
so they are using more than the 4 lines and it makes it too little if your neighbors tell you that it is too little to read, click in the bubble and scroll all the way down, you could have something left at the very bottom you don't see as well.
If it is too little then delete all of it and remember to only use 4 lines and no more.
