I work with a team of 6 designers and we are all experiencing regular and multiple different issues with Share for Review – we are all using the latest version 2021 and are needing to try multiple things each time with varied results to get Share for Review to work – these include:
1. Restarting Indesign
2. Logging and in about of Adobe CC
3. Trashing preferences
4. Saving a file Copy

Ths is extremely frustrating, wasting a lot of time and energy and money – I am sincerely hoping you are aware of all of these issues and are working hard to resolve it. Its a real shame as this feature is incredible when working properly. We rely heavily on this feature now so hopefully will be sorted soon ;)

One issue not shown in the screenshots is the blank screen we get sometimes when clicking the Share for Review feature.
