Text/msn group message chat not syncing with all member
I have an issue with a text / msn message Group of 3. Before my IOS 8 update it worked without any issue. Now whenever I send a message to anyone in the group it goes directly to them and not in the group. The other 2 members are fine - when they send a message to the group in goes in the group. Whenever I send a message in the group it goes to them individually. I have read that one way around this is to delete the group and re-create it it, this will solve the problem, however if I do that I loose all the chat history in the group along with photos etc which I want to avoid loosing. Does anyone have a solution or workaround to this as am looking to fix the group without deleting and re-creating.
Thanks in advance
