Issues with prototyping

Hey there,
I've been having this issue since the update yesterday (15/09/2021). I have no idea whats happening, I don't know if I've missed something really obvious or what. The prototyping has worked for the previous screens but I got to the fourth screen and here are the problems I'm experiencing:
- Adding a drag option when it hasn't been selected
- Not being able to save my work
- Prototype links disappear and don't work
- The software is generally just behaving strangely
- I go back to Design view and its still in Prototype view and I can't edit anything
- Some prototype links are working, such as the menu overlays etc., but I can't add any new links
Really odd. I've got some deadlines due so this is quite frustrating. I've tried saving it locally instead of the cloud but it made no difference.
Any help you could provide would be muchly appreciated 😄
