I don’t have a URL, but I do have an eml file saved from a LinkedIn email that does not display the full content in eM Client.
What I have noticed is that all these emails that do not load correctly, will ‘sometimes’ eventually loads after several minutes, but when checking the same emails in alternative mobile email apps such as ‘Samsung Email’ or ‘Maildroid’ it works 100% every time.
The problem I am experiencing is exactly the the same as another user you have been helping here → emClient Android doesn't show body of email
I have also done the same steps referenced in your post above. Clearly there is an issue with the eM Client mobile app.
Look forward to hearing from you regarding next steps.
