Hi @sarah.a.1905 and @Holly and thank you for reaching out 
I am sorry you haven’t had access to tasks recently. I confirm that everything is working fine for you; your profiles are set correctly and you have listed your language pairs you can work on. This should help to find the tasks in these language pairs when they are available 
The homepage only shows the tasks the correspond with your language pairs, whether the filters are used or not. In general, the tasks available may not stay there for a long time, this is to say, the homepage shows tasks available at the time you are looking, and new tasks can be posted in any minute, so keep an eye out 
Also, I changed your preferences to receive email notifications when tasks are available. Hope you have the chance to find tasks soon 
Let us know if you need any assistance
