"Unable To Download" .ICS file into iOS 11
I am currently using an iPhone 7. iOS version 11.2.1
The app I use for email is the native "Mail" app in iPhone with a gmail account. Same with Calendar. At work, I have a rule that sends all meeting invites from my work Exchange account to my personal email account, for the sole purpose that I can view upcoming work meetings from my personal phone.
The forwarding process works fine. I get all the invites on my phone. When I try to download the .ICS file attached to the invite, I cannot. "Unable to download" is the message I receive. I am unable to add the meeting to my calendar. When I'm on my desktop, log into my gmail account, and find the same forwarded invite, I can accept the invite without issue.
I'm not doing something the right way. I've reviewed the various forums, and I can't find someone sharing the same issue.
I will provide any additional information I've missed.
