@fitter2gether Welcome to the Fitbit family! Thanks for taking the time to post the experience you have had so far with Ionic and Sony Xperia E5.
That is correct. According to the list of compatible devices, the Xperia E5 is not supported. Same thing for Deutsche bank with Fitbit Pay.
he developer team is aware of the need to add new devices to the list of compatible devices. There are some users who can synchronize with non-compatible devices. If your phone meets the requirement of Minimum Supported OS (Android 5.0 Lollipop), you can try the tips on this helpful article.
Note that we don't guarantee that the synchronization will be successful as we are still testing on this phone model.
As for the bank; please create a Feature Suggestion asking for it to be compatible.
Keep me posted!
