Hi, I use confluence for my school notes, diary, etc. I love this product.
One of the features I use all the time, is to create links between my documents. I normally do this by press CTRL+K and it always provides a list of suggestions as I type.
For some reason, it has stopped providing me with suggestions - it is very difficult now to just write & link notes.
I use Firefox on Linux, but I also tried Google-Chrome on Linux and got the same result.
Not sure how I can troubleshoot this...Pls let me know what information you require; I'll do my best to provide it to you.
Not sure if the image bellow helps, normally I'd get a series of suggestions when I type in the link.

Thanks in advance!
