I have an iPhone that runs 13.3.1 (latest at this time). It's a corporate phone and has an MDM profile installed. I've been using the phone for almost 2 years now with a custom keyboard (Google Keyboard). However, after recently traveling to the States, I noticed that my phone is forcing me to use the default Apple keyboard every time I try to type something. It's been happening since 3 weeks now and this change was not caused by a system upgrade, I remember not changing/installing anything around the time when this started. It's almost like my iPhone woke up one day and did not want me to use another keyboard, even after I had been using one for years now (jealous much?). The MDM profile installed doesn't mention having control over keyboard. The moment I start typing, I get force switched to the Apple keyboard (without suggestions). And while I can switch to the Apple keyboard with suggestions, I can't use my other keyboard even though it's set as default.
This behavior began very randomly and at this point I wonder if it's just paranoia or legit. I work in this field and so it probably isn't irrational paranoia but I'm just looking for a logical answer. Does anyone know what this is about or has experienced similar?
