Allow me to understand the issue a little better here. Can you please provide the Mattermost Server version that you are on?
I have the problem described above with a server with version 5.22.2, but I tested many other server versions and a bug that I always get is a crash when trying to type in the chat.
Additionally, you mentioned that the issue happens on all iDevices running iOS 10. Based on the mobile changelog, we start to support iOS 11+ starting 1.17.0:
iPhone 5s devices and later with iOS 11+ is required.
I see you are in a hurry to no longer support older mobile devices but the in the AppStore you are already less in a hurry. That’s a problem because people will not read the github change log before updating their app.
Since the devices are running on the older iOS, what models are you referring to? Are they able to upgrade to the latest version of iOS?
I have an iPhone 5s with iOS 10.3.1 which is supported according to the AppStore. I could update it to iOS 12.4.7, that could explain why not so many people are impacted, but I don’t want to do the update because I am afraid that I will lose some apps and my phone will be slower.
If I am not wrong the last working version for iOS 10.3 was 1.30.1, but it’s up to you to explain, the only way I know to install an app is with the AppStore.
How can you do that? If you give me a .ipa it would not be signed with my account so my iPhone will not accept it, do I miss something?
The app releases in the AppStore should work with the supported environment by default (iPhone 5s devices and later with iOS 11+ is required). Can you please confirm again if the affected users are running on the supported platforms? If yes, I would like to gather more details on the issue such as the screen shot / screen recording of the problem as well as verifying if the problem happens on all iOS users in the server.
If you need I give you a screenshot, you can see that iOS 10.3 is supported in the current mobile version (1.32.0):
I can give you a link also:
(In fact not, a message told me that I can’t post more than 2 links. That was a link to the AppStore webpage, but maybe you can find it by yourself.)
