Details: We have integrated Box UIElements into our Salesforce community application. Box UIElements Explorer and Preview are integrated as Static resources in the Salesforce org and are loaded and called by Aura components. We are using Explorer 14.0.0 and Preview 2.42.0, with core-js 2.5.3 (polyfills). Salesforce Mobile Publisher is used to generate an iOS app and an Android app. The Box components work fine in Desktop Browsers, Mobile Browsers and the Android app, but (only) in the iOS app, the Box Preview hangs while trying to load a file. Is there anyone out there who has iOS app w/ Box integrated experience who has come across this issue or can offer some ideas as to why Preview is not loading, or knows how something about how this can be resolved? Thank you!
