Charge 5 won’t keep a charge and lightning storm background now black display after update

"I have called 3 times after the recent update to my Fitbit charge 5.  It has worked great up until then.  I, like many, have had all the problems above, from past charge lasting a wk to now 2-3 hours, lighting storms showing on the screen to now a black screen. Had just renewed my Premium acct., and waiting on word whether that could be transferred to a newer Fitbit or not.  Seems I should get that back if it doesn’t transfer to a new Fitbit since current one not working AND wasn’t my fault with the update.  No part of this seems reasonable or a good practice for a company when there are other options of fitness devices from apple to Garmin.  Just very frustrated with a 35% off coupon and a new band but no offering of my $79 back?
Can see 49,000 + are also just as frustrated.  When iPhone updates screw up, they immediately fix it.  And yes, have restarted multiple times and all the tricks many have tried to fix this. 
Frustrating…….HELP1"

Hi, @Comet21 , your Premium subscription is specific to you, not to a specific device, so yes, you will continue to enjoy all Premium features available for your new device if you add a different device to your account.

Thanks for that information, I have recommended to several of my patients in the past, (and still do) how great and reasonably priced these are but wasn’t sure now with all this. Nothing lasts forever but appreciate the response.
